1. Unit Overview & The Big Picture
Unit 1, “Foundations of American Democracy,” is the biggest single unit on the AP Gov exam — it makes up roughly
15–22% of the multiple-choice section, more than any other unit, and its content (especially the foundational
documents) reappears throughout the Free Response section all year.
Unit 1 asks one overarching question: how do you build a government powerful enough to function, but
limited enough to protect individual liberty? Every topic in this unit — from Hobbes and Locke to federalism
today — circles back to that same tension.
This unit is also where you meet most of the course's required Foundational Documents for the first time: the
Declaration of Independence, the Articles of Confederation, the Constitution, Federalist No. 10, Federalist No. 51, and
Brutus No. 1. Knowing WHO wrote each one, WHAT side of a debate it represents, and WHY it matters is tested
constantly — including in the mandatory document-based Concept Application FRQ.
The 3 Things Your Teacher Wants You to Walk Away Knowing:
• The Founders rejected the Articles of Confederation because it created a national government too weak to
function — and then debated how much power the new Constitution should give the national government
instead.
• Federalist No. 10 and Brutus No. 1 represent the two sides of the ratification debate: Federalists (Madison)
wanted a strong, large republic to control factions; Anti-Federalists (Brutus) feared a strong central government
would destroy liberty and the states.
, • Federalism — the division of power between national and state governments — is not fixed. It has shifted over
time (dual → cooperative → modern debates over devolution), and the Supreme Court (McCulloch v. Maryland,
U.S. v. Lopez) has redrawn its boundaries repeatedly.
2. Key Concepts (Official College Board Framework)
The College Board organizes Unit 1 into nine required topics (1.1–1.9). Know each one well enough to apply it to a
new scenario or excerpt — not just recite the vocabulary.
Topic 1.1 — Ideals of Democracy
• Natural rights (Locke): life, liberty, and property exist independent of government and cannot be legitimately
taken away.
• Social contract: people consent to give up some freedom to a government in exchange for protection of their
rights — government's legitimacy comes from the consent of the governed.
• Popular sovereignty, republicanism, and limited government are the core ideals reflected in the Declaration of
Independence and the Constitution.
Topic 1.2 — Types of Democracy
• Participatory, pluralist, and elite theories describe different views of how democracy actually works in practice
— the U.S. system reflects elements of all three.
Topic 1.3 — Government Power and Individual Rights
• Hobbes's “state of nature” (life without government) is chaotic and dangerous — government is necessary to
prevent disorder, but too much government power threatens the very liberty it's meant to protect.
• A balance between governmental power and individual rights has been a hallmark of American political
development from the Founding to today.
Topic 1.4 — Challenges of the Articles of Confederation
• The Articles created a weak national government: no power to tax, no power to regulate interstate commerce,
no national executive or judiciary, and amendment required unanimous consent of all 13 states.
• Shays' Rebellion (1786–87), an armed uprising of indebted farmers in Massachusetts, exposed the national
government's inability to respond to crises and became the catalyst for the Constitutional Convention.
Topic 1.5 — Ratification of the U.S. Constitution
• Key compromises made ratification possible: the Great (Connecticut) Compromise (bicameral Congress — equal
representation in the Senate, proportional in the House), the Three-Fifths Compromise, and the Electoral
College.
• The promise of a Bill of Rights was the key concession that won over enough Anti-Federalists to secure
ratification.
Topic 1.6 — Principles of American Government
• Separation of powers divides government into three branches (legislative, executive, judicial); checks and
balances give each branch tools to limit the others — both are defended in Federalist No. 51.
• Federalism — dividing power between a national government and state governments — is the third major
structural principle, layered on top of separation of powers.
Topic 1.7 — Relationship Between the States and National Government
• Powers are divided into enumerated (national government only), reserved (state governments, via the 10th
Amendment), and concurrent (both levels, e.g., taxation).
