Every term in Unit 3

All 41 terms we publish for Period 3: 1754–1800, 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.

Republican motherhood
The idea that women served the republic by raising virtuous citizens. Justified female education while confining women to the household.
Proclamation of 1763
British ban on colonial settlement west of the Appalachians after Pontiac’s War. Significance: the first postwar imperial measure to anger colonists, signaling the end of salutary neglect and frustrating land speculators and veterans alike.
Federalist No. 10
Madison’s argument that a large republic controls the “mischiefs of faction” by multiplying interests so no single one can dominate. Significance: reversed the classical assumption that republics must be small, and remains the core defense of extended federal government.
French and Indian War
Removed France from North America and left Britain with enormous debt — the debt that produced colonial taxation and the imperial crisis.
Albany Plan of Union (1754)
Franklin's rejected proposal for colonial confederation for defense; an early precedent for later union.
Stamp Act (1765)
First direct internal tax on the colonies. Provoked the Stamp Act Congress and the principle "no taxation without representation".
Virtual representation
British claim that Parliament represented all subjects regardless of who voted. Colonists rejected it, insisting on actual representation.
Townshend Acts (1767)
Duties on imports including tea, with revenue paying royal officials' salaries — removing them from colonial assemblies' financial control.
Boston Massacre (1770)
Five colonists killed by British troops. Revere's engraving turned a street brawl into propaganda; Adams's defense of the soldiers showed commitment to rule of law.
Committees of Correspondence
Intercolonial communication networks that spread grievances and coordinated resistance — the organizational spine of the Revolution.
Boston Tea Party (1773)
Destruction of East India Company tea in response to the Tea Act, which threatened colonial merchants with a monopoly even while lowering the price.
Coercive Acts (1774)
Closed Boston's port, restructured Massachusetts government and expanded quartering. Meant to isolate Massachusetts; instead unified the colonies.
Common Sense (1776)
Paine's pamphlet arguing in plain language for independence and against monarchy itself. Sold enormously and shifted opinion from reconciliation to separation.
Declaration of Independence
Jefferson's statement of natural rights, consent of the governed and the right of revolution, followed by grievances against the King.
Battle of Saratoga (1777)
American victory that convinced France to enter openly — the war's turning point, since French money, troops and navy made Yorktown possible.
Articles of Confederation
First national government: one vote per state, no power to tax or regulate commerce, amendment by unanimity. Deliberately weak and unable to respond to crisis.
Northwest Ordinance (1787)
Set orderly admission of new states as equals, funded public schools and banned slavery north of the Ohio — the Articles' most durable achievement.
Shays' Rebellion (1786–87)
Indebted Massachusetts farmers closed courts to stop foreclosures. Its suppression by private militia convinced elites the Articles were unworkable.
Great Compromise
Bicameral Congress: representation by population in the House, equal by state in the Senate. Resolved the large-state/small-state deadlock.
Three-Fifths Compromise
Counted three of every five enslaved people for representation and taxation, inflating Southern power in the House and Electoral College for decades.
Federalists vs Anti-Federalists
Federalists wanted a strong central government and ratification; Anti-Federalists feared distant tyranny and demanded a bill of rights, which they won.
Bill of Rights (1791)
First ten amendments, added to satisfy Anti-Federalists; enumerated protections against federal power.
Hamilton's financial plan
Assume state debts, create a national bank, tax whiskey and protect manufacturing — aimed at binding creditors to the new government.
Whiskey Rebellion (1794)
Western Pennsylvania farmers resisted the excise; Washington led troops to suppress it, showing the new government could enforce law where the Articles could not.
Washington's Farewell Address
Warned against permanent foreign alliances and the "baneful effects" of party spirit; cited for a century to justify non-entanglement.
Alien and Sedition Acts (1798)
Federalist laws lengthening naturalization and criminalizing criticism of the government, used against Republican editors.
Virginia and Kentucky Resolutions
Madison and Jefferson argued states could judge federal laws unconstitutional — the seed of nullification and later states' rights doctrine.
Actual vs virtual representation
Parliament claimed every member represented the whole empire; colonists insisted a legislature may tax only those who elected it. The real content of "no taxation without representation."
Sugar Act (1764)
Lowered the molasses duty while adding vice-admiralty enforcement and juryless trials — the first revenue act aimed at the colonies, and the start of the constitutional argument.
Quartering Act (1765)
Required colonies to house and supply British troops. Its resentment fed directly into the Third Amendment.
Declaratory Act (1766)
Repealed the Stamp Act while asserting Parliament's authority to legislate for the colonies "in all cases whatsoever" — conceding the tax and keeping the principle.
Dunmore's Proclamation (1775)
Virginia's royal governor offered freedom to enslaved people who fled Patriot enslavers and joined British forces; thousands did, and it hardened slaveholding Patriots against reconciliation.
Lord Dunmore's Ethiopian Regiment
Formation of formerly enslaved men in British service, wearing "Liberty to Slaves" — proof that revolutionary language cut in more than one direction.
Battle of Yorktown (1781)
Washington and Rochambeau trapped Cornwallis with decisive French naval support at the Chesapeake, ending major fighting and forcing negotiations.
Treaty of Paris (1783)
Recognized American independence with generous boundaries to the Mississippi. Said nothing enforceable about Native nations, who had not been party to it and lost the most.
Land Ordinance of 1785
Surveyed the Northwest into six-mile townships with a section reserved for schools — the grid still visible from the air over the Midwest.
Judiciary Act of 1789
Created the federal district and circuit courts and the office of Attorney General; its Section 13 is the provision Marbury v. Madison struck down.
Bank of the United States (1791)
Hamilton's twenty-year chartered bank holding federal deposits and issuing notes. The test case for loose construction and the origin of the strict-versus-loose divide.
Neutrality Proclamation (1793)
Washington's declaration of American neutrality in the war between Britain and France, which enraged pro-French opinion and helped harden the party division.
Jay's Treaty (1794)
Secured British withdrawal from Northwest posts but conceded on neutral shipping rights and impressment. Republicans read it as submission to Britain.
Pinckney's Treaty (1795)
Spain granted navigation of the Mississippi and deposit rights at New Orleans, plus the 31st parallel boundary — a major win for Western farmers.
