Period 3 runs from 1754 to 1800 - from the outbreak of the Seven Years' War to the end of John Adams's presidency. It contains the Revolution, but the exam treats the Revolution as an effect, so start with its cause.

Colonial rivalry between Britain and France intensified in the mid-eighteenth century as a growing colonial population pressed westward. The Seven Years' War 七年战争, known in North America as the French and Indian War 法印战争, settled that rivalry.

Britain won, and three consequences follow directly:

• A major expansion of territory 领土大扩张 - France was removed from mainland North America.
• An enormous war debt 巨额战争债务, which Britain decided the colonies should help repay.
• Restrictions on westward movement, notably the Proclamation of 1763 1763年公告线, intended to prevent costly conflict with American Indians but resented by colonists who wanted the land they had just helped win.

That is the chain the exam wants: victory produced debt and new territory, and managing both required tighter control of the colonies.

New British efforts to collect taxes 征税 without the consent of colonial assemblies, and to assert imperial authority, provoked organised resistance.

Colonial leaders based their arguments on the rights of British subjects 英国臣民的权利, on the ideals of the Enlightenment 启蒙思想, and on their own long experience of self-government - the assemblies built up during Period 2.

Resistance was not only argument. Facing shortages and, in some regions, British military occupation 军事占领, men and women both took part: boycotts of British goods, home manufacture, crowd action, and committees of correspondence. Leaders such as Benjamin Franklin 富兰克林 energised the movement, and the slogan of the period is "no taxation without representation" 无代表不纳税.

Enlightenment ideas led American political thinkers to emphasise individual talent over hereditary privilege 才能重于世袭特权, and to assert the natural rights 天赋权利 of the people and the sovereignty of the people 人民主权.

Two ideas do most of the work in essays:

• Republicanism 共和主义 - government rests on the consent of the governed, and citizens must show virtue by placing the public good above private interest.
• Natural rights - rights that exist before government, which government is created to protect, and whose violation justifies resistance.

The war for independence succeeded through a combination of colonial resolve, difficult terrain, and crucially foreign assistance 外国援助, above all from France.

The Revolution's ideals then spread further than its leaders intended:

• They inspired movements to abolish slavery 废奴运动, especially in the North, and gradual emancipation laws.
• They raised questions about the status of women 妇女地位, expressed in the idea of republican motherhood 共和母亲身份 - that women shaped the republic by raising virtuous citizens.
• They influenced later revolutions elsewhere in the Atlantic world.

At the same time the expansion of slavery into the deep South and adjacent western lands continued, alongside rising antislavery 反奴隶制 sentiment - a contradiction the course returns to repeatedly.

After declaring independence, leaders wrote new constitutions and declarations of rights 宪法与权利宣言 that reflected republican ideals, generally limiting executive power.

The Articles of Confederation 邦联条例 created a deliberately weak central government: no power to tax, no power to regulate commerce, no executive, and no national judiciary. It succeeded in organising western settlement through the Northwest Ordinance 西北法令, but could not manage debt, trade disputes, or unrest.

The Constitutional Convention 制宪会议 of 1787 produced a stronger national government built on compromise 妥协, including the Great Compromise 大妥协 over representation and compromises over slavery and commerce.

Ratification 批准 was contested. Federalists 联邦党人 argued the new government was strong enough to govern yet checked enough to be safe; Anti-Federalists 反联邦党人 feared centralised power and demanded protection for individual liberties, which produced the Bill of Rights 权利法案.

Under George Washington 华盛顿 and John Adams 亚当斯, political leaders disagreed sharply over the relationship between the national and state governments 联邦与各州的关系, economic policy, and foreign policy. Those disagreements hardened into the first party system 第一政党体系.

War between France and Britain after the French Revolution 法国大革命 forced hard choices, and the government pursued diplomatic initiatives to deal with the continued British and Spanish presence in North America. Washington's Farewell Address 华盛顿告别演说 urged national unity and warned against political factions and permanent foreign alliances.

Meanwhile a distinctive national culture 民族文化 developed - in art, literature, and architecture - alongside continued regional variation.

American Indian groups repeatedly evaluated and adjusted their alliances 重新评估并调整结盟 with European powers and the new United States as circumstances changed.

Growing numbers of migrants moved west, intensifying competition over resources, boundaries, and trade 资源、边界与贸易. The relationship between the federal government and American Indian tribes remained ambiguous 含混不清, contributing to recurring conflict. In the Southwest, the Spanish expanded their mission system 传教团体系, supported by the bonded labour of local American Indians.

The period's reasoning skill is continuity and change 延续与变化. The strongest answers hold both: political institutions changed radically, while slavery, westward expansion, and conflict with American Indians continued and intensified.

Worked example (a real AP exam question). The 2025 exam asked, as part B of a short-answer question, "Briefly describe one effect of the Seven Years' War from 1754 to 1765." A full-mark answer names one effect and shows it is an effect: "Britain emerged from the war with a large debt, which led Parliament to impose new taxes such as the Stamp Act on the colonies to help pay for imperial defence." Notice the shape: describe one effect needs the causal link stated, not just a fact from the period. "Britain won the war" is a result, not an effect on what followed; "the colonies were angry" is too vague to credit.

• Learn the causal chain: war → debt and new territory → taxes and the Proclamation of 1763 → colonial resistance → independence.
• Republicanism and natural rights are the two ideas to name; do not just write "Enlightenment ideas".
• For the Constitution, argue from the specific weakness it fixed - no power to tax, no power to regulate commerce, no executive.
• Keep Federalist and Anti-Federalist positions straight, and remember the Bill of Rights was the price of ratification.
• The Revolution's effects on slavery and women are examinable, and both are partial: ideals spread further than rights did.
• On continuity-and-change prompts, give one of each. An answer that only lists changes has answered half the question.
