Every term in Unit 1

All 30 terms we publish for Foundations of American Democracy, with definitions. Reading them through is the fastest way to find the ones you cannot define — then drill those in cram mode until you can produce them without the prompt.

Federalism

Sovereignty divided between national and state governments, each acting directly on citizens within its sphere.

Tenth Amendment

Reserves to the states or the people powers not delegated to the federal government. The textual anchor of states' rights arguments.

Commerce clause

Gives Congress power over interstate commerce. Read broadly since Gibbons and especially since the New Deal; narrowed somewhat in US v. Lopez.

Necessary and proper clause

Grants Congress power to make laws needed to execute its enumerated powers. The constitutional basis of most federal expansion.

Natural rights

Locke's claim that life, liberty and property precede government. Government exists to protect them, and forfeits legitimacy when it does not.

Social contract

People surrender some freedom to a government in exchange for protection of their rights, and may replace a government that breaks the bargain.

Popular sovereignty

Political authority rests with the people. Expressed in "We the People" and in every mechanism that ties officials to elections.

Republicanism

Governing through elected representatives rather than direct popular vote — chosen partly to filter passion through deliberation.

Participatory democracy

Emphasizes broad direct participation by ordinary citizens; reflected in town meetings, initiatives and referenda.

Pluralist democracy

Group-based participation, in which organized interests compete and bargain, and policy emerges from that competition.

Elite democracy

Limited participation, in which a small number of well-informed or well-resourced people make most decisions. The Electoral College reflects this strand.

Declaration of Independence

Required document. States natural rights, consent of the governed and the right to alter or abolish a destructive government, then lists grievances.

Articles of Confederation

Required document. A league of states: no power to tax or regulate commerce, no executive or judiciary, and amendment only by unanimity.

Shays' Rebellion

Armed uprising of indebted farmers that the Confederation could not suppress, which supplied the argument for a stronger central government.

Constitution of the United States

Required document. Establishes separation of powers, checks and balances, federalism, and an amendment process demanding supermajorities.

Federalist No. 10

Required document. Madison argues a large republic controls faction best, because many competing interests make a tyrannical majority hard to assemble.

Brutus No. 1

Required document. Anti-Federalist warning that a republic cannot govern so large a territory, and that the necessary and proper and supremacy clauses will swallow the states.

Federalist No. 51

Required document. "Ambition must be made to counteract ambition" — separation of powers works because officeholders defend their own institution's prerogatives.

Federalist No. 70

Required document. Argues for a single energetic executive, since one person acts with decision and can be held accountable in a way a council cannot.

Federalist No. 78

Required document. Defends life tenure and judicial review; the judiciary is "least dangerous" because it controls neither sword nor purse.

Letter from a Birmingham Jail

Required document. King defends nonviolent direct action and civil disobedience against unjust laws, addressed to white moderates urging patience.

Great Compromise

Population-based House and equal-state Senate, resolving the Virginia and New Jersey plans.

Three-Fifths Compromise

Counted three of every five enslaved people for representation and taxation, inflating Southern power in the House and Electoral College.

Separation of powers

Legislative, executive and judicial functions in distinct branches, so no single body both makes and enforces law.

Checks and balances

Each branch can block the others — veto and override, advice and consent, judicial review, impeachment.

Enumerated vs implied powers

Enumerated powers are listed in Article I Section 8; implied powers flow from the necessary and proper clause, as confirmed in McCulloch.

Supremacy clause

Federal law and treaties override conflicting state law. The mechanism by which national policy binds the states.

Categorical vs block grants

Categorical grants come with strict conditions on how money is spent; block grants give states discretion within a broad purpose.

Unfunded mandate

A federal requirement imposed on states without accompanying money, a persistent source of federal-state friction.

Fiscal federalism

Using federal money and its conditions to shape state policy — the main lever now that direct commands are constitutionally constrained.

What examiners penalize here

• When a free-response prompt names a foundational document, do not just summarize it — **apply its argument** to the scenario. For Federalist 10, name factions and the large-republic remedy; for Brutus 1, name the fear of a distant, consolidated government and the small-republic ideal.
• Pair the cases as a contrast: **McCulloch expanded** federal power (implied powers + supremacy), while **Lopez limited** it (commerce power has bounds; reserved powers matter). Free-response prompts love asking you to compare a required case with a non-required one, so know which direction each pushed.

Practice US Gov

Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
