The Civil War and Reconstruction
The Civil War was the deadliest conflict in American history and the turning point of the 1800s. It ended slavery and settled whether the nation would stay united. The period after it, Reconstruction, tried to rebuild the South and define freedom for millions of formerly enslaved people. Both come up often on the test.
The Civil War (1861–1865) was fought between the Northern states (the Union) and Southern states that seceded (the Confederacy). Reconstruction (1865–1877) was the effort afterward to reunite the country and secure rights for freed African Americans.
Causes of the War
The central issue was slavery — especially whether it would expand into new western territories. The South’s economy depended on enslaved labor, while opposition to slavery grew in the North. Disputes over states’ rights and the election of Abraham Lincoln in 1860 pushed Southern states to secede and form the Confederacy. When Confederate forces fired on Fort Sumter in 1861, the war began.
The War and Its Outcome
The Union had more people, factories, and railroads; the Confederacy had strong generals and was fighting to defend its own territory. A turning point came with the Emancipation Proclamation (1863), which declared enslaved people in the rebelling states free and made ending slavery a war goal. The Union won in 1865. The Thirteenth Amendment then abolished slavery throughout the country.
Reconstruction
Reconstruction aimed to rebuild the South and protect the rights of freed people. Three amendments were central: the Thirteenth (ended slavery), the Fourteenth (granted citizenship and equal protection), and the Fifteenth (protected Black men’s right to vote). But resistance was fierce. After federal troops withdrew in 1877, Southern states passed Jim Crow laws enforcing segregation, and many of Reconstruction’s gains were rolled back — setting up the civil rights struggles of the next century.
