The Constitution, Federalism, and Amendments

The Constitution is the rulebook for the entire U.S. government. It sets up the branches, divides power between the nation and the states, and lays out how it can be changed. Understanding its structure — and the idea of federalism — unlocks a large share of the civics questions on the test.

The Constitution is the supreme law of the land. Federalism is the system it creates for splitting power between the national (federal) government and the state governments. And the amendment process is the official way to change the Constitution over time.

What the Constitution Does

The Constitution opens with the Preamble ("We the People"), then uses articles to set up the three branches and their powers, and finally allows amendments to add or change rules. It replaced the Articles of Confederation, under which Congress lacked independent taxing power and reliable enforcement authority. The Constitution created a stronger central government while still protecting the states and the people.

Federalism: Sharing Power

Federalism means power is shared between the federal government and the states. Some powers belong only to the federal government, some only to the states, and some to both.

The national government alone can coin money, declare war, and make treaties. States hold primary responsibility for election administration, public schools, and driver's licensing, subject to federal constitutional and statutory limits. Both levels can tax, build roads, operate courts, and enact laws within their authority. When valid federal law conflicts with state law, the Supremacy Clause gives valid federal law priority.

The Amendment Process

The founders made the Constitution hard — but not impossible — to change. An amendment must be proposed (usually by a two-thirds vote in both houses of Congress) and then ratified (approved) by three-fourths of the states. Because it takes such broad agreement, only 27 amendments have passed in over 200 years. The first ten are the Bill of Rights. This high bar keeps the Constitution stable while still allowing change.
