AP World History Modern Quick Review

After the Abbasid Caliphate's political power faded, Islamic political authority fragmented into regional sultanates while Islamic religious and cultural unity persisted.

The Mongols sacked Baghdad in 1258, ending the Abbasid Caliphate as a political center. The Delhi Sultanate (est. 1206) brought Islamic rule to South Asia and imposed the jizya tax on non-Muslims. Sufi missionaries (e.g., in West Africa and South Asia) spread Islam through syncretic, mystical practice rather than conquest.

The Abbasid Caliphate (religious/political center, destroyed 1258) vs. the Ottoman Empire (rising Turkic state that later claimed the caliphate after 1517) --- they are sequential, not simultaneous peaks.

Students assume Islamic civilization declined after Baghdad's fall in 1258; instead power decentralized into competing sultanates (Delhi, Mamluk Egypt) while trade and scholarship continued.

Baghdad falls 1258 $arrow$ power fragments $arrow$ Delhi Sultanate + Sufis spread Islam via syncretism.

Song, Yuan, and early Ming China combined a highly centralized bureaucracy with commercial dynamism, while Southeast Asian states like Srivijaya and the Khmer Empire thrived on maritime and agrarian wealth.

Song China (960--1279) restored and expanded the civil service exam based on Confucian classics, fueling meritocratic bureaucracy. Economic innovations included Champa rice (faster-maturing, enabling population growth), flying cash (early paper currency), and proto-industrial iron/steel output. The Mongols founded the Yuan Dynasty (1271--1368) under Kublai Khan. The Khmer Empire (Angkor) and Srivijaya controlled Southeast Asian maritime trade routes.

Confucianism (this-worldly ethical/social philosophy stressing filial piety and hierarchy) vs. Neo-Confucianism (Song-era synthesis blending Confucian ethics with Buddhist and Daoist metaphysics).

Do not describe the civil service exam system as a Yuan invention --- it long predates the Mongols and was actually reduced in importance under Mongol rule, which favored ethnic hierarchy over merit.

Song = exam meritocracy + Champa rice + flying cash $arrow$ Yuan = Mongol overlay on China.

Sub-Saharan African states built wealth and political power by controlling trans-regional trade in gold, salt, ivory, and slaves.

The Mali Empire, whose political capital was Niani, peaked under Mansa Musa (r. 1312--1337), whose 1324 hajj to Mecca famously disrupted Cairo's gold market through lavish spending; Mansa Musa also annexed Timbuktu, developing it into a major center of trade and Islamic scholarship rather than a political capital. Great Zimbabwe (stone-walled city, no mortar) grew wealthy from gold and ivory trade to the Indian Ocean. Swahili Coast city-states (Kilwa, Mombasa, Mogadishu) blended Bantu and Arab/Islamic culture, producing the Swahili language, and traded via dhows across the Indian Ocean.

Mali (West African, trans-Saharan gold-salt trade, Islamic ruling class) vs. Great Zimbabwe/Swahili Coast (East/Southeast African, Indian Ocean trade, Bantu-based societies with Islamic coastal influence).

Mansa Musa's hajj is often cited only as a display of wealth; the exam more often rewards explaining its economic consequence (gold price inflation/devaluation in Mediterranean markets).

Mansa Musa 1324 hajj $arrow$ gold floods Cairo $arrow$ Mali on the map of Europe.

Complex, populous societies in the Americas and Pacific developed sophisticated political, agricultural, and trade systems in relative isolation from Afro-Eurasia before 1492.

The Mississippian culture (Cahokia, near modern St. Louis) built massive earthen mounds and supported a large maize-based population by c. 1200. The Aztec (Mexica) Empire, founded at Tenochtitlan in 1325, and the Inca Empire, consolidating in the Andes by the 1400s, both used tribute systems to control conquered peoples. Pacific Islander societies (Polynesia) used advanced wayfinding/navigation to settle and maintain trade networks across vast ocean distances.

Aztec tribute empire (indirect rule, conquered states pay tribute but keep local rulers) vs. Inca command economy (direct administrative control, mit'a labor tax, extensive road system, no market exchange).

Students describe pre-1450 American societies as isolated and simple; the exam instead expects recognition of large-scale urbanization (Tenochtitlan rivaled European cities in size) and extensive regional trade networks.

Cahokia mounds + Aztec tribute + Inca mit'a + Polynesian wayfinding = complex societies before contact.

Overland Silk Road networks connected East Asia, Central Asia, the Middle East, and Europe, spreading goods, technology, disease, and religion along caravan routes.

Key goods: Chinese silk and porcelain moving west; horses, glassware, and precious metals moving east. Buddhism spread from India into Central Asia and China via Silk Road missionaries and monasteries (e.g., cave complexes like Dunhuang). Caravanserais provided lodging, security, and market exchange for merchants. The Black Death (bubonic plague) likely spread west along these routes in the 1300s, carried by fleas on rodents traveling with caravans.

Silk Roads (overland, Central Asian caravan routes) vs. Indian Ocean trade (maritime, monsoon-dependent, higher volume of bulk goods).

Exam questions often ask for a specific technology or belief system that spread via the Silk Roads (e.g., Buddhism, gunpowder, papermaking) --- vague answers like ``ideas spread'' will not earn full credit.

Silk west, horses east, Buddhism spreads, caravanserais rest stops, plague rides along too.

Monsoon winds enabled a vast, multi-ethnic maritime trade system linking East Africa, the Middle East, South Asia, and China, moving far greater volumes of goods than overland routes.

Traders used dhows (Arab/Indian lateen-sail ships) and Chinese junks. Key ports included Calicut, Malacca, Hormuz, and the Swahili city-states. Cargo included spices (pepper, cloves), textiles, porcelain, and ivory. Zheng He's Ming Chinese treasure fleet voyages (1405--1433) projected Chinese power and collected tribute across the Indian Ocean before being abruptly halted.

Zheng He's voyages (state-sponsored tribute/diplomatic missions, ended by imperial decision) vs. later European voyages of exploration (privately/state-financed, aimed at establishing permanent colonial/commercial control).

Students assume China's withdrawal from Indian Ocean voyages after 1433 meant it withdrew from trade entirely; private Chinese merchants continued extensive commerce despite the official fleet's end.

Monsoons + dhows/junks $arrow$ spices, porcelain, ivory $arrow$ Zheng He 1405--1433 then stops.

Camel caravans crossing the Sahara linked West African gold and salt resources to North African and Mediterranean markets, spreading Islam southward in the process.

Gold-salt trade: West African gold moved north; Saharan salt (mined at sites like Taghaza) moved south, often trading at near-equal weight. The camel saddle innovation made large-scale desert caravan trade feasible. Islam spread into West Africa primarily via merchants and Sufi missionaries along these trade routes, not military conquest.

Trans-Saharan trade (desert caravan, camel-based, gold-salt) vs. trans-Atlantic slave trade (much later, ocean-based, coerced labor to the Americas) --- do not conflate the two ``trans-'' systems.

The exam expects students to link trade routes to religious/cultural diffusion (Islam in West Africa), not just economic exchange --- a purely economic answer misses half the point.

Camel saddle $arrow$ gold north, salt south $arrow$ Islam spreads via merchants, not swords.

The Mongol conquests (early 1200s--1300s) created the largest contiguous land empire in history, and the resulting political unity temporarily made overland Eurasian trade safer and more efficient.

Genghis Khan (Temujin) unified the Mongol tribes in 1206 and began rapid conquest. The empire split into khanates (Yuan China, Ilkhanate in Persia, Golden Horde in Russia, Chagatai Khanate in Central Asia). The ``Pax Mongolica'' (Mongol Peace) protected merchants along the Silk Roads, enabling travelers like Marco Polo to cross Eurasia. Mongols also facilitated the spread of the Black Death by connecting previously separated disease pools.

Mongol conquest (extremely violent, destroyed cities like Baghdad) vs. Mongol administration (often religiously tolerant, promoted trade and communication once territory was secured).

Students overstate Mongol destruction alone; the CED emphasizes the paradox that violent conquest was followed by administrative policies that increased connectivity and exchange.

Genghis unites 1206 $arrow$ khanates split empire $arrow$ Pax Mongolica safe trade $arrow$ plague travels too.

The Ottoman, Safavid, and Mughal empires used gunpowder weapons (cannons, muskets) to consolidate vast, centralized, multi-ethnic land empires in the early modern period.

All three empires combined military technology with bureaucratic administration and claimed religious legitimacy (Sunni Ottomans, Shia Safavids, Muslim Mughals ruling a Hindu-majority population). Each used tax-farming or land-grant systems to fund standing armies and administer distant provinces.

Gunpowder empires (early modern, land-based, Islamic dynasties: Ottoman/Safavid/Mughal) vs. maritime empires (Portugal, Spain, later Britain/Netherlands --- sea-based, focused on trade-route and colonial control).

Students treat the three gunpowder empires as identical; the exam rewards distinguishing their differing religious sects and specific administrative tools (millet system vs. mansabdari system).

Cannons + centralized bureaucracy + religious legitimacy = Ottoman, Safavid, Mughal formula.

The Ottoman Empire used military conquest, religious tolerance under the millet system, and centralized bureaucracy to rule a vast multi-ethnic, multi-religious realm from the Balkans to the Middle East and North Africa.

Mehmed II conquered Constantinople in 1453, ending the Byzantine Empire and renaming the city Istanbul. The devshirme system conscripted Christian boys (mainly Balkan) to serve as elite Janissary soldiers/administrators. The millet system granted religious communities (Christians, Jews) autonomy over internal affairs in exchange for loyalty and taxes (jizya). Suleiman the Magnificent (r. 1520--1566) presided over the empire's political, cultural, and military peak.

Devshirme (conscription of Christian boys into Ottoman service, a path to elite status) vs. jizya (a tax paid by non-Muslim subjects who remained in their communities).

Millet system tolerance is often mistaken for full religious equality; non-Muslims retained autonomy but paid extra taxes and had a formally subordinate legal status.

1453 Constantinople falls $arrow$ devshirme Janissaries + millet tolerance + jizya tax $arrow$ Suleiman's peak.

The Safavid Empire made Twelver Shia Islam the state religion of Persia, creating a lasting religious divide with its Sunni Ottoman rivals.

Founded by Ismail I in 1501, the Safavids forcibly converted the Persian population to Shia Islam. Shah Abbas I (r. 1588--1629) revived the empire, moving the capital to Isfahan and building a professional military corps (ghulam) modeled partly on the Ottoman Janissaries. Sustained Ottoman-Safavid conflict (Sunni vs. Shia) weakened both empires over time.

Safavid Persia (Shia Islam, Persian/Iranian identity) vs. Ottoman Empire (Sunni Islam, Turkish/Anatolian core) --- their rivalry was as much religious as territorial.

Students conflate Safavid and Mughal history because both are Islamic land empires of the same era; keep Safavid (Shia, Persia, Isfahan) distinct from Mughal (Sunni ruling class, South Asia, Hindu majority).

Ismail I 1501 $arrow$ forced Shia conversion $arrow$ Abbas I + Isfahan $arrow$ rivalry with Sunni Ottomans.

The Mughal Empire brought a Muslim ruling dynasty to a Hindu-majority South Asia, alternating between policies of religious syncretism/tolerance and religious orthodoxy depending on the ruler.

Babur founded the empire after defeating the Delhi Sultanate at the First Battle of Panipat (1526). Akbar the Great (r. 1556--1605) promoted religious tolerance, abolished the jizya tax on Hindus, and created Din-i Ilahi, a syncretic court philosophy. Aurangzeb (r. 1658--1707) reversed this, reimposing the jizya and pursuing more orthodox Sunni policies, straining the empire's stability. The Taj Mahal (built under Shah Jahan, completed 1653) exemplifies Mughal architectural fusion of Persian, Islamic, and Indian styles.

Akbar's tolerant, syncretic policies vs. Aurangzeb's orthodox, exclusionary policies --- the exam frequently tests this contrast to show how religious policy affected imperial stability.

Do not assume all Mughal rulers were uniformly tolerant or uniformly harsh; policy varied significantly by ruler and this variation is a common short-answer prompt.

Babur 1526 Panipat $arrow$ Akbar tolerant (no jizya) $arrow$ Aurangzeb orthodox (jizya back) $arrow$ empire strains.

Ming and Qing China and Tokugawa Japan pursued state consolidation through centralized bureaucracy, agricultural growth, and, at times, deliberate restriction of foreign contact.

The Ming Dynasty (1368--1644) restored Han Chinese rule after the Yuan, rebuilt the Great Wall, and later limited foreign trade to controlled ports (e.g., Canton system precursors). The Qing Dynasty (Manchu, 1644--1912) expanded territory significantly and maintained Han Chinese cooperation through a dual bureaucracy. Tokugawa Japan (1603--1868) enforced sakoku (``closed country'') policy, severely restricting foreign trade (limited to a Dutch outpost at Nagasaki) while maintaining strict social hierarchy under the shogunate.

Qing China's selective trade restriction (still engaged in substantial foreign commerce, e.g., silver trade) vs. Tokugawa Japan's sakoku (much stricter near-total isolation from Europeans).

``Isolationism'' is often overstated for Qing China; unlike Tokugawa Japan's near-total sakoku, Qing China continued large-scale silver-based trade (notably with Spanish America via Manila).

Ming restores Han rule $arrow$ Qing (Manchu) dual bureaucracy $arrow$ Tokugawa sakoku closes Japan except Dutch at Nagasaki.

Technological innovation, state sponsorship, and the desire to bypass Ottoman-controlled overland trade routes drove Portugal and Spain to pioneer transoceanic voyages beginning in the 1400s.

Key technologies: the caravel (maneuverable ship), astrolabe and magnetic compass (navigation), and improved cartography. Prince Henry the Navigator sponsored Portuguese voyages down the African coast. Vasco da Gama reached India by rounding Africa in 1498. Christopher Columbus, sailing for Spain, reached the Caribbean in 1492, seeking a westward route to Asia. The 1494 Treaty of Tordesillas divided newly claimed non-European territory between Spain and Portugal.

Portuguese strategy (establish fortified trading posts/factories along existing Indian Ocean networks) vs. Spanish strategy (conquest and direct territorial colonization in the Americas).

Columbus is often wrongly credited with ``discovering'' a route to Asia; he died believing he had reached Asia, and it was da Gama's 1498 voyage that achieved an actual sea route to India.

Caravel + astrolabe + compass $arrow$ da Gama 1498 to India, Columbus 1492 to Caribbean $arrow$ Tordesillas splits the world.

Sustained contact between the Eastern and Western Hemispheres after 1492 triggered a massive, permanent biological exchange of crops, animals, and diseases with transformative and often devastating global effects.

From the Americas to Afro-Eurasia: maize, potatoes, tomatoes, cacao, tobacco --- these crops boosted population growth in Europe, Africa, and Asia. From Afro-Eurasia to the Americas: horses, cattle, pigs, wheat, sugarcane --- and, catastrophically, diseases like smallpox and measles, to which Indigenous Americans had no immunity, causing population collapse (estimates of 80--90% decline in some regions over the following century).

Columbian Exchange (biological/agricultural transfer of plants, animals, disease) vs. transatlantic slave trade (forced human migration for labor) --- related but analytically distinct processes, though both stem from post-1492 contact.

Exam prompts often require explaining WHY disease impact was so asymmetric (Indigenous Americans lacked prior exposure/immunity to Afro-Eurasian pathogens due to centuries of isolation) rather than simply stating that ``many people died.''

Americas give maize/potato/tobacco; Afro-Eurasia gives horses/wheat/smallpox $arrow$ population boom there, collapse here.

European demand for plantation labor in the Americas fueled a massive, brutal forced migration of enslaved Africans across the Atlantic, reshaping societies on three continents.

An estimated 12+ million enslaved Africans were transported via the Middle Passage between roughly 1500 and the 1800s, with significant mortality en route. African states and merchants (e.g., in West/Central Africa) participated as suppliers, often obtaining captives through warfare, raiding, and existing regional slave systems, which Europeans then scaled up dramatically. The triangular trade linked Europe (manufactured goods), Africa (enslaved people), and the Americas (raw materials like sugar, cotton, tobacco).

Chattel slavery in the Americas (hereditary, race-based, permanent, treated as legal property) vs. earlier forms of slavery/bondage in Africa and Eurasia (often not strictly hereditary, sometimes allowed paths to freedom or social reintegration).

Students sometimes claim Europeans single-handedly captured all enslaved Africans; the CED expects recognition that African political and merchant elites were active, essential intermediaries in supplying captives, alongside European demand and shipping.

12M+ Africans, Middle Passage, triangular trade $arrow$ chattel slavery = hereditary + race-based + permanent.

European colonizers in the Americas relied on a range of coerced and semi-coerced labor systems --- varying by colonial power and region --- to extract wealth from mining and agriculture.

The encomienda system (Spanish) granted colonists the right to forced Indigenous labor and tribute in exchange for ``protection'' and Christianization. The mita was an Andean/Inca-origin rotational labor draft that Spain adapted, notably to staff the silver mines at Potosi. Plantation slavery (chattel, African-descent, hereditary) dominated in Brazil, the Caribbean, and the southern British colonies. Indentured servitude (contracted, temporary, often European in the early period, later including Asian laborers post-abolition) was another coerced labor form.

Encomienda (labor/tribute grant over Indigenous communities, nominally not ownership of people) vs. chattel slavery (outright legal ownership of enslaved individuals as property, hereditary status).

The mita is frequently misattributed as a purely Spanish invention; it was an Inca institution that Spanish colonizers adapted and intensified for mining, especially at Potosi.

Encomienda = tribute/labor grant; mita = Inca-origin mining draft (Potosi); chattel slavery = hereditary property.

European states pursued mercantilist economic policy --- maximizing exports, minimizing imports, and hoarding precious metals --- through colonial control and chartered trading companies.

Mercantilism held that global wealth was fixed, so colonies existed to enrich the mother country by supplying raw materials and buying finished goods. Joint-stock companies (e.g., the Dutch VOC, founded 1602, and the English East India Company, founded 1600) pooled investor capital and held state-chartered monopolies over trade in specific regions. Spanish American silver (mined at Potosi and Zacatecas) flowed globally, including to China via the Manila Galleon trade, fueling a genuinely global silver-based economy.

Mercantilism (state-directed, zero-sum, colonies serve the metropole) vs. capitalism/free trade (later ideology, associated with Adam Smith, favoring market competition over state control) --- mercantilism dominates this unit's period, not free-market capitalism.

Students underestimate how directly silver connected China to the Atlantic World; the Manila Galleon route linking Spanish America to Ming/Qing China via the Philippines is a frequently tested specific connection.

Mercantilism = fixed wealth + hoard silver; VOC/East India Co. = chartered monopolies; Manila Galleon links Potosi silver to China.

Enlightenment ideas about natural rights, social contract, and popular sovereignty provided the intellectual justification for a wave of political revolutions challenging monarchical and colonial authority.

Key thinkers: John Locke (natural rights to life, liberty, property; government by consent), Jean-Jacques Rousseau (general will, social contract), Montesquieu (separation of powers). The American Revolution (1775--1783) produced a republic explicitly citing Enlightenment natural-rights language in the Declaration of Independence (1776). The French Revolution (beginning 1789) overthrew the monarchy, produced the Declaration of the Rights of Man and of the Citizen, and radicalized into the Reign of Terror (1793--1794) before Napoleon's rise.

American Revolution (colonial independence movement, kept existing social/economic structures largely intact, notably preserving slavery) vs. French Revolution (internal social revolution that abolished the monarchy and feudal privilege and attempted more radical social restructuring).

Exam questions expect a specific Enlightenment thinker linked to a specific revolutionary document/principle --- a generic ``Enlightenment ideas influenced revolutions'' answer without a named thinker or text scores poorly.

Locke natural rights $arrow$ American 1776; Rousseau/Montesquieu $arrow$ French 1789, Rights of Man, then Terror.

The Haitian Revolution (1791--1804) was the only successful large-scale slave revolt in history to result in an independent state, directly inspired by and radicalizing the ideals of the French Revolution.

Enslaved and free people of color in Saint-Domingue rebelled beginning in 1791. Toussaint Louverture emerged as the revolution's key military and political leader, though he was captured by French forces and died in French captivity in 1803. Jean-Jacques Dessalines declared independence in 1804, founding Haiti as the first Black-led republic and the second independent nation in the Americas after the United States.

Haitian Revolution (enslaved people seizing freedom and independence through armed revolt) vs. Latin American independence movements (largely led by criollo elites seeking political autonomy from Spain, not primarily abolition of slavery).

Students often forget the direct causal link to France: Saint-Domingue was a French colony, and revolutionary chaos and shifting French policy on slavery (abolished 1794, later threatened by Napoleon) directly shaped the revolution's trajectory.

1791 revolt $arrow$ Toussaint Louverture leads $arrow$ Dessalines declares independence 1804 $arrow$ first Black republic.

Inspired by Enlightenment ideas and the examples of the American, French, and Haitian Revolutions, criollo elites across Spanish and Portuguese America led independence movements in the early 1800s, but the new nations largely preserved existing racial and class hierarchies.

Simon Bolivar (``the Liberator'') led independence movements across northern South America (Gran Colombia, Venezuela, etc.). Jose de San Martin led forces liberating Argentina, Chile, and helped Peru. Napoleon's 1808 invasion of Spain, which removed the Spanish king, created a power vacuum that accelerated Latin American independence movements. Brazil gained independence from Portugal peacefully in 1822 under Dom Pedro I, remaining a monarchy rather than becoming a republic.

Bolivar's campaigns (northern South America: Venezuela, Colombia, Ecuador) vs. San Martin's campaigns (southern South America: Argentina, Chile, Peru) --- the exam may ask which leader operated in which region.

Students assume independence produced full social equality; in most new Latin American republics, criollo elites retained power while Indigenous peoples, enslaved Africans, and mixed-race populations largely remained marginalized.

Napoleon invades Spain 1808 $arrow$ power vacuum $arrow$ Bolivar (north) + San Martin (south) $arrow$ Brazil independent 1822 as monarchy.

Beginning in Britain in the mid-1700s, the Industrial Revolution transformed production from hand labor to machine-based manufacturing, fundamentally restructuring economies, societies, and global power relationships.

Britain's advantages included access to coal and iron, a stable banking/credit system, colonial raw materials (especially cotton), and a large labor supply. Key innovations: the steam engine (improved by James Watt), the spinning jenny and power loom (textile mechanization), and later railroads. Industrialization spread to Belgium, Germany, the United States, and Japan (Meiji era) by the later 1800s, while most of the colonized world was pushed into supplying raw materials rather than industrializing.

First Industrial Revolution (textiles, steam power, coal/iron, c. 1750--1850, centered on Britain) vs. Second Industrial Revolution (steel, electricity, chemicals, oil, c. 1870--1914, more globally distributed including the U.S. and Germany).

Exam questions frequently ask WHY Britain industrialized first --- a full-credit answer names multiple specific factors (coal/iron, capital, colonial cotton supply, labor availability), not just ``Britain had good technology.''

Coal + iron + capital + colonial cotton $arrow$ Britain first $arrow$ steam engine, spinning jenny $arrow$ spreads to US, Germany, Japan.

Nationalism --- the belief that people sharing language, culture, or ethnicity should govern themselves as a unified state --- drove the consolidation of new nation-states in the 19th century.

Italian unification (completed 1871) was led politically by Camillo di Cavour (Piedmont-Sardinia) and militarily by Giuseppe Garibaldi. German unification (1871) was engineered by Otto von Bismarck through ``blood and iron'' policy, including the Franco-Prussian War (1870--1871), culminating in Wilhelm I's proclamation as German Emperor. Japan's Meiji Restoration (1868) replaced the Tokugawa shogunate, ending sakoku isolation and launching rapid, state-directed industrialization and Western-style military/political reform to avoid colonization.

Italian and German unification (nationalism used to UNIFY previously fragmented states/principalities into one nation) vs. nationalism in multi-ethnic empires like Austria-Hungary or the Ottoman Empire (nationalism instead threatened to FRAGMENT existing states along ethnic lines).

The Meiji Restoration is sometimes mislabeled a ``revolution from below''; it was largely a top-down, elite-driven modernization project aimed explicitly at preserving Japanese sovereignty against Western imperialism.

Cavour/Garibaldi $arrow$ Italy 1871; Bismarck blood and iron $arrow$ Germany 1871; Meiji 1868 $arrow$ Japan modernizes fast.

Industrialization's social disruptions and inequalities generated competing economic ideologies about how production and wealth should be organized.

Adam Smith's ``The Wealth of Nations'' (1776) articulated free-market capitalism, arguing an ``invisible hand'' of self-interest and competition efficiently allocates resources with minimal state interference. Utopian socialists (e.g., Robert Owen) proposed cooperative, planned communities as alternatives to industrial exploitation. Karl Marx and Friedrich Engels's ``The Communist Manifesto'' (1848) argued history is driven by class struggle and predicted the proletariat (working class) would overthrow the bourgeoisie (owning class) to establish a classless, communist society.

Socialism (broad term: state or collective ownership/control of production, gradual or revolutionary paths) vs. Marxism/communism specifically (a particular revolutionary theory predicting inevitable proletarian revolution and eventual stateless classless society).

Do not describe Marx's ideas as immediately widely implemented in the 1800s --- his direct influence on actual governments (Russia, China) is a 20th-century (post-1917) phenomenon, tested in later units.

Smith = invisible hand/free market; Marx and Engels 1848 = class struggle, proletariat vs. bourgeoisie.

The harsh conditions of early industrial capitalism (child labor, dangerous factories, urban overcrowding) provoked organized labor movements and government reform efforts.

Labor unions organized strikes and collective bargaining to demand better wages, hours, and safety. Britain's Factory Acts (throughout the 1800s) progressively restricted child labor and regulated working hours. Urbanization produced severe overcrowding, pollution, and public health crises, spurring reform movements (sanitation, housing). Women's labor and suffrage movements grew partly out of industrial-era organizing experience, connecting economic and political reform demands.

Trade unionism/labor reform (working within the capitalist system to improve conditions) vs. revolutionary socialism/Marxism (seeking to overthrow the capitalist system entirely) --- both responded to industrialization but proposed very different solutions.

Exam prompts about industrialization's ``effects'' expect BOTH economic/material changes (wages, urbanization) AND social/political responses (unions, reform laws, suffrage movements) --- listing only factory conditions without reform responses is incomplete.

Bad conditions $arrow$ unions strike + Factory Acts limit child labor $arrow$ reform movements grow from labor organizing.

Industrialized Western powers (and Japan) used superior military technology and economic motives to seize direct or indirect colonial control over most of Africa and large parts of Asia in the late 1800s.

The Berlin Conference (1884--1885) had European powers divide African territory among themselves with no African representation, ignoring existing ethnic and political boundaries --- driving the ``Scramble for Africa.'' Justifications included Social Darwinism and the civilizing mission (e.g., Rudyard Kipling's ``White Man's Burden''). Technological tools of empire included the Maxim gun (rapid-fire weapon), steamships, and quinine (enabling survival in malaria-prone regions). Forms of colonial control varied: direct rule (e.g., French assimilation policy) vs. indirect rule (e.g., British use of existing local rulers, as in Nigeria).

Direct rule (colonizer administers territory using its own officials, often to assimilate colonized peoples into the colonizer's culture, as France generally preferred) vs. indirect rule (colonizer governs through existing local elites/structures, as Britain generally preferred).

Students often forget to name a specific technology (Maxim gun, quinine, steamship) when explaining HOW a small number of Europeans conquered vast, populous regions --- ``better weapons'' alone is too vague for full credit.

Berlin Conference 1884--85 carves Africa $arrow$ Maxim gun + quinine + steamships enable conquest $arrow$ direct (France) vs. indirect (Britain) rule.

Colonized peoples resisted imperial domination through both armed rebellion and reform movements, even as colonial economies were restructured to extract raw materials for the benefit of the metropole.

The Indian Rebellion of 1857 (Sepoy Mutiny) began among Indian soldiers in British service and became a broader, though ultimately unsuccessful, revolt; its suppression led Britain to transfer control from the East India Company directly to the British Crown. The Boxer Rebellion (1899--1901) in China was an anti-foreign, anti-Christian uprising suppressed by an international coalition of foreign powers, further weakening the Qing Dynasty. Cash-crop economies (e.g., cotton in Egypt, rubber in the Congo Free State under brutal Belgian exploitation) reoriented colonial agriculture toward export commodities rather than local food needs.

Indian Rebellion of 1857 (military-origin revolt, led to direct British Crown rule of India) vs. Boxer Rebellion 1899--1901 (popular anti-foreign uprising in a still-nominally-independent Qing China, suppressed by multinational foreign intervention).

Students sometimes describe both rebellions as ``successful'' since they are famous; both were militarily defeated by imperial/foreign powers, though each had significant long-term political consequences.

1857 Sepoy revolt $arrow$ Crown rule replaces East India Co.; 1899--1901 Boxer Rebellion $arrow$ crushed, Qing weakened further.

Industrialization and the decline of the transatlantic slave trade (Britain abolished its slave trade in 1807) drove new large-scale global migration patterns, especially indentured labor from Asia.

After the British Empire abolished slavery (1833) and the slave trade earlier, indentured servitude --- especially of Indian and Chinese laborers --- filled labor demand on plantations (e.g., in the Caribbean, Fiji, Mauritius) and in railroad/mining projects (e.g., Chinese laborers on U.S. railroads). Push factors included population pressure and economic hardship in sending regions (China, India, Southern/Eastern Europe); pull factors included labor demand and perceived opportunity in industrializing/plantation economies. This period produced lasting global diaspora communities.

Indentured servitude (contract-based, fixed term, technically ``voluntary'' though often coerced by poverty/deception) vs. chattel slavery (permanent, hereditary, no contract, full legal ownership) --- the exam expects you to note indentured servitude's abuses while distinguishing it structurally from slavery.

Do not describe indentured servitude simply as ``a milder form of slavery'' without qualification --- while conditions were often brutal and coercive, the CED wants recognition of the specific contractual/temporal difference from chattel slavery.

Slave trade ends (Britain 1807/1833) $arrow$ indentured Indian/Chinese labor fills gap $arrow$ new global diasporas form.

A combustible mix of militarism, alliance systems, imperialism, and nationalism turned a regional Balkan crisis into a global war after the assassination of Archduke Franz Ferdinand in 1914.

MAIN causes: Militarism (arms race, especially naval), Alliances (Triple Alliance: Germany/Austria-Hungary/Italy vs. Triple Entente: France/Russia/Britain), Imperialism (colonial rivalries), Nationalism (especially Slavic nationalism in the Balkans, and Franco-German tension over Alsace-Lorraine). The war introduced new destructive technology: machine guns, poison gas, trench warfare, tanks, and submarines, producing unprecedented casualties. The U.S. entered in 1917. The Treaty of Versailles (1919) imposed harsh reparations and a ``war guilt clause'' on Germany, sowing resentment that contributed to future conflict.

Triple Alliance (Germany, Austria-Hungary, Italy --- though Italy switched sides in 1915) vs. Triple Entente/Allied Powers (France, Russia, Britain, later joined by the U.S. and Italy).

Students name only the assassination of Franz Ferdinand as ``the cause'' of WWI; the exam wants the assassination framed as the SPARK/trigger while MAIN factors are identified as the underlying, long-term causes.

MAIN causes $arrow$ 1914 assassination sparks it $arrow$ new tech (gas, tanks, trenches) $arrow$ 1919 Versailles blames Germany.

Economic collapse and political instability after WWI enabled the rise of revolutionary communism in Russia and fascist/totalitarian dictatorships in Europe, setting the stage for a second global war.

The Russian Revolution of 1917 had two phases: the February Revolution toppled Tsar Nicholas II, and the October Revolution brought the Bolsheviks under Vladimir Lenin to power, leading to Russia's exit from WWI (Treaty of Brest-Litovsk, 1918) and a subsequent civil war. The Great Depression (triggered by the 1929 U.S. stock market crash) caused global economic devastation, fueling political extremism. Benito Mussolini's Fascist Party seized power in Italy (1922); Adolf Hitler's Nazi Party rose to power in Germany (1933), exploiting resentment over Versailles and economic hardship. Joseph Stalin consolidated totalitarian control in the USSR, implementing forced collectivization and Five-Year industrialization Plans.

Fascism (Italy/Germany: ultra-nationalist, anti-communist, allied with business/military elites, glorifies the state/nation) vs. Communism (USSR: internationalist in theory, claims to abolish class and private property, one-party state controlling the economy).

Students sometimes equate fascism and communism as ``the same'' because both were totalitarian; the exam rewards distinguishing their opposing economic ideologies (state-directed capitalism/nationalism vs. state ownership/collectivism) even while noting shared authoritarian methods.

1917 Lenin/Bolsheviks; 1929 crash $arrow$ Depression $arrow$ Mussolini 1922, Hitler 1933, Stalin's five-year plans.

Aggressive expansion by Germany, Italy, and Japan --- driven by fascist/militarist ideology and unresolved WWI grievances --- triggered a truly global war fought across Europe, Africa, Asia, and the Pacific.

Germany's invasion of Poland (September 1, 1939) began the European war; Japan's expansion in Asia (including the invasion of Manchuria in 1931 and full-scale war with China from 1937) and attack on Pearl Harbor (December 7, 1941) brought the U.S. into a fully global conflict. The Allied Powers (Britain, USSR after 1941, U.S. after 1941, China) defeated the Axis Powers (Germany, Italy, Japan). The war ended in Europe in May 1945; the Pacific war ended after the U.S. dropped atomic bombs on Hiroshima and Nagasaki (August 1945).

WWI alliance blocs (Triple Alliance/Entente) vs. WWII alliance blocs (Axis: Germany/Italy/Japan vs. Allies: Britain/USSR/U.S./China) --- do not carry WWI alliance names into a WWII answer.

The exam expects awareness that the USSR and U.S. were NOT always Allies against Germany --- the USSR only joined the Allies after Germany broke the Nazi-Soviet Pact and invaded in June 1941, and the U.S. only entered after Pearl Harbor in December 1941.

1939 Poland invaded $arrow$ 1941 USSR invaded + Pearl Harbor $arrow$ Allies vs. Axis $arrow$ 1945 atomic bombs end it.

The early-to-mid 20th century saw state-organized mass killing on an industrial scale, most notably the Armenian Genocide during WWI and the Holocaust during WWII.

The Ottoman government's Armenian Genocide (beginning 1915) killed an estimated 1--1.5 million Armenians through forced deportation, starvation, and massacre, framed by the Ottoman state as a wartime security measure against a supposedly disloyal minority. The Holocaust, orchestrated by Nazi Germany, systematically murdered approximately 6 million Jews and millions of others (Roma, disabled people, political dissidents, gay people) via ghettos, mass shootings, and extermination/concentration camps (e.g., Auschwitz-Birkenau) as part of an explicit racial ideology.

Armenian Genocide (WWI-era, Ottoman Empire, 1--1.5 million killed, framed around wartime loyalty) vs. the Holocaust (WWII-era, Nazi Germany, 6 million Jews killed plus other targeted groups, driven by explicit racial extermination ideology).

Exam short-answer prompts on 20th-century mass atrocities expect specific death-toll magnitude, perpetrator state, and stated ideological justification --- not just ``many people were killed.''

1915 Armenian Genocide (Ottoman) $arrow$ 1--1.5M; Holocaust (Nazi Germany, WWII) $arrow$ 6M Jews + others.

After WWII, the U.S. and USSR emerged as rival global superpowers whose ideological, political, and military competition (capitalism/democracy vs. communism) shaped world affairs without direct war between them from roughly 1947 to 1991.

Containment (U.S. policy to stop the spread of communism) underpinned the Truman Doctrine (1947, aid to Greece/Turkey) and the Marshall Plan (1948, economic aid to rebuild Western Europe). Germany, and Berlin specifically, was divided; the Berlin Wall (built 1961, fell 1989) became the era's defining symbol of division. Proxy wars--- conflicts where the superpowers backed opposing sides without fighting each other directly --- included the Korean War (1950--1953) and the Vietnam War (U.S. involvement escalating through the 1960s, ending 1975). NATO (1949, Western military alliance) and the Warsaw Pact (1955, Soviet-led alliance) formalized the military standoff.

Containment (U.S. strategy: PREVENT the spread of communism to new areas) vs. rollback (a more aggressive, less consistently applied strategy aiming to actively REVERSE existing communist control) --- containment was the dominant, consistently applied U.S. policy.

Students sometimes describe the Cold War as involving direct U.S.-USSR military combat; the defining feature tested is that the superpowers avoided DIRECT war with each other, instead fighting via proxy conflicts and an arms/space race.

Truman Doctrine + Marshall Plan = containment $arrow$ Berlin Wall 1961--1989 $arrow$ proxy wars: Korea, Vietnam.

After WWII, weakened European empires and rising nationalist movements led to the rapid political independence of most African and Asian colonies, though the process was often violent and left enduring economic and political challenges.

India gained independence from Britain in 1947, immediately followed by the violent Partition of India and Pakistan along religious lines, displacing millions and causing enormous loss of life; Mohandas Gandhi's nonviolent resistance (satyagraha) had been central to the independence movement. Ghana, led by Kwame Nkrumah, became the first sub-Saharan African colony to gain independence (1957), inspiring further African decolonization. The Algerian War of Independence (1954--1962) against France was notably violent on both sides before Algeria won independence.

Peaceful/negotiated decolonization (e.g., Ghana's relatively orderly transition, India's independence itself though accompanied by violent Partition) vs. violent, prolonged independence wars (e.g., Algeria against France, Vietnam against France then the U.S.).

Students conflate India's 1947 independence (largely a negotiated transfer of power) with Partition's violence (a catastrophic, separate humanitarian crisis) --- the exam expects both to be named as distinct events/consequences.

Gandhi's satyagraha $arrow$ India/Pakistan independence & Partition 1947; Nkrumah $arrow$ Ghana 1957 first in sub-Saharan Africa.

Many newly independent and developing states sought to avoid taking sides in the Cold War, instead forming their own cooperative political blocs to assert independent global influence.

The Bandung Conference (1955, Indonesia) brought together Asian and African states (including leaders like Indonesia's Sukarno, India's Nehru, and Egypt's Nasser) to promote Afro-Asian solidarity and opposition to colonialism. This laid groundwork for the Non-Aligned Movement (formally founded 1961), which sought a ``third way'' distinct from both the U.S.-led and Soviet-led Cold War blocs. Movements for self-determination also continued within existing states, such as ongoing anti-apartheid resistance in South Africa (Nelson Mandela's African National Congress).

Non-Aligned Movement (states formally refusing to align with EITHER Cold War superpower bloc) vs. proxy-war states (nations that became direct arenas of superpower competition, like Korea or Vietnam, despite sometimes claiming nonalignment).

``Non-aligned'' does not mean ``uninvolved in world affairs''; non-aligned states actively organized (Bandung, then the formal Non-Aligned Movement) to exert collective diplomatic influence on Cold War and decolonization issues.

Bandung 1955 $arrow$ Non-Aligned Movement 1961 $arrow$ ``third way'' between US and USSR blocs.

Newly independent nations after WWII faced the challenge of building stable political institutions and economies, often while contending with artificial colonial-era borders and continued economic dependency on former colonizers.

Many post-colonial borders (especially in Africa, drawn at the Berlin Conference) grouped rival ethnic groups together or split unified ones apart, contributing to post-independence conflict (e.g., Nigerian Civil War/Biafra, 1967--1970; Rwandan ethnic tension rooted partly in colonial-era Belgian policy). Economic strategies varied: import substitution industrialization (producing domestic goods to replace imports) was tried in parts of Latin America and elsewhere; many states remained economically dependent on exporting raw materials (a continuation of colonial-era economic patterns, sometimes termed neocolonialism).

Decolonization (formal political/legal transfer of sovereign independence) vs. neocolonialism (continued informal economic/political dependency and foreign influence over a nominally independent state) --- political independence did not guarantee economic independence.

Students treat 1945--1970s decolonization as instantly resolving all colonial-era problems; the CED specifically tests understanding that artificial borders and economic dependency persisted as major post-independence challenges.

Colonial borders ignore ethnicity $arrow$ post-independence conflict; raw-material export dependency continues = neocolonialism.

Since the mid-20th century, rapid advances in technology and transportation, combined with new international economic institutions, have accelerated global economic integration.

The Bretton Woods Conference (1944) established the International Monetary Fund (IMF) and World Bank to stabilize and rebuild the post-WWII global economy. The General Agreement on Tariffs and Trade (GATT, 1947) evolved into the World Trade Organization (WTO, established 1995), promoting reduced trade barriers globally. The Green Revolution (mid-20th century, associated with Norman Borlaug) used high-yield crop varieties, fertilizers, and irrigation to dramatically increase agricultural output, especially in Asia and Latin America. Multinational corporations and container shipping (standardized shipping containers) drove the late-20th-century boom in global trade.

IMF (short-term financial stability, loans to countries facing balance-of-payments crises) vs. World Bank (long-term development financing and infrastructure/poverty-reduction projects) --- distinct Bretton Woods institutions with different core missions.

The Green Revolution is often described only positively; the exam also expects awareness of its downsides/critiques --- dependency on expensive fertilizer/pesticide inputs, environmental strain, and uneven benefits favoring larger landowners.

Bretton Woods 1944 $arrow$ IMF + World Bank; GATT $arrow$ WTO 1995; Green Revolution boosts yields, has costs too.

Twentieth- and twenty-first-century migration has been driven by economic opportunity, political conflict, and persecution, producing large-scale, often controversial, movements of people across national borders.

Labor migration flowed from lower-income to higher-income regions (e.g., Mexico/Latin America to the U.S.; South/Southeast Asia and North Africa to Europe and the Gulf states). Refugee crises resulted from wars and political persecution (e.g., displacement from WWII, the Vietnam War, and numerous late-20th/21st-century conflicts). Migration produced both economic benefits (remittances sent home, labor filling shortages) and social/political tensions (anti-immigrant backlash, debates over assimilation and national identity) in receiving countries.

Labor migrants (moving primarily for economic opportunity, generally voluntary) vs. refugees (fleeing war, persecution, or disaster, often involuntary/forced displacement) --- exam prompts may ask you to classify a given migration scenario correctly.

Students describe modern migration as one-directional (poor to rich countries only); the exam also rewards awareness of remittances flowing back to origin countries, creating genuine two-way economic linkages.

Labor migration = economic pull; refugees = forced by conflict/persecution $arrow$ remittances flow back home.

Globalization since 1900 has spread cultural products and political ideas worldwide while also provoking transnational movements demanding human rights and highlighting cultural backlash/resistance.

The United Nations' Universal Declaration of Human Rights (1948) established an influential international human-rights standard following the atrocities of WWII. Global feminist movements pushed for women's political, economic, and social rights across many nations in the late 20th century. Popular culture (film, music, fast food, fashion) spread globally through mass media and multinational corporations, provoking both enthusiastic adoption and ``cultural imperialism'' critiques/resistance (e.g., movements to protect local languages and traditions).

Cultural diffusion (voluntary adoption/blending of foreign cultural elements) vs. cultural imperialism (a critical framing emphasizing unequal power --- dominant nations' culture displacing or overwhelming local/indigenous cultures).

The Universal Declaration of Human Rights (1948) is a non-binding UN declaration, not enforceable international law; students should not describe it as a treaty with binding legal enforcement mechanisms.

UDHR 1948 sets global rights standard $arrow$ feminist movements spread $arrow$ pop culture spreads + provokes cultural-imperialism backlash.

The late 20th and early 21st centuries have been shaped by the end of the Cold War, accelerating environmental crises, and new forms of transnational conflict that existing nation-state institutions struggle to address.

The Cold War ended with the fall of the Berlin Wall (1989) and the dissolution of the Soviet Union (1991), ending the bipolar world order. Environmental challenges --- climate change, deforestation, resource depletion --- have become defining global issues, addressed (with limited success) through international agreements such as the Kyoto Protocol (1997) and Paris Agreement (2015). Transnational terrorism (e.g., the September 11, 2001 attacks by al-Qaeda) prompted new global security concerns and conflicts that cross traditional national boundaries. International organizations (UN, WHO, WTO) increasingly address problems --- pandemics, climate, trade --- that no single nation-state can solve alone.

Cold War-era bipolar conflict (state vs. state, U.S. vs. USSR) vs. post-Cold War transnational threats (terrorism, climate change, pandemics --- often not organized around a single rival nation-state).

Students sometimes treat 1991 as the simple ``end of history''/end of global conflict; the exam instead expects recognition that new, different challenges (terrorism, environmental crisis, economic inequality amid globalization) replaced the bipolar Cold War conflict rather than conflict disappearing.

1989 Wall falls, 1991 USSR dissolves $arrow$ bipolar order ends $arrow$ new era: climate accords, 9/11 terrorism, global institutions.
