Continuity and Change in Period 3

By the end of this lesson, students will be able to:

• Apply the three components of the AP Continuity and Change reasoning process (3.i, 3.ii, and 3.iii) to developments drawn from across Period 3, 1754 to 1800.
• Identify, on each of eight thematic axes, at least one significant shift and one stubborn continuity between the imperial moment of 1754 and the early Republic of 1800.
• Account for why some inheritances of the colonial era survived the Revolution and the Constitution intact, even as the formal political order was rebuilt.
• Argue, with specific evidence drawn from at least three points across the period, whether change or continuity is the more historically consequential pattern.
• Construct an LEQ thesis that defends a defensible position on a Continuity-and-Change prompt and that identifies a specific historical context for the argument.

From a distance, Period 3 looks like a single sweeping transformation. Imperial subjects became republican citizens. A British provincial economy became the foundation of an Atlantic trading nation. A scattered set of colonial assemblies became a federal Constitution with a Bill of Rights. The story is real, and the AP exam rewards students who can tell it with precision. The trouble is that the same forty-six-year window also reveals something else: how much survived. The men who held office in 1800 were, by and large, the same men who had held it in 1774. The plantation economy was larger, not smaller. Slavery had been written into the federal Constitution rather than written out of it. The Anglo-American legal tradition still framed every state court. A thesis that captures only the change misses the more interesting historical question, which is why so much persisted across a revolution that was supposed to remake everything.

The synthesis task that closes Unit 3 is therefore double-sided. Students need a vocabulary for the changes (republicanism, federalism, disestablishment, party formation, the doctrine of consent) and a vocabulary for the continuities (elite governance, racial slavery, common-law marriage, Anglo-Protestant cultural framework, agrarian dominance). The AP Continuity and Change reasoning process is the tool that organizes the two together. It asks students to identify a pattern, to account for what produced it, and to weigh its significance. None of those moves is optional on the rubric. The LEQ analysis point goes only to responses that move beyond identification into causation and significance.

Three caution lines are worth drawing at the start of this lesson. First, change and continuity are not opposites in any simple sense. The Revolution decisively shifted the source of political legitimacy from the Crown to the people, and yet the people who exercised that new sovereignty were, in 1800, an even narrower slice of the population than in some colonial assemblies of the 1760s. The shift in principle and the continuity of practice happened simultaneously (KC-3.2.II.D). Second, the same development can carry both threads. The federal Constitution was the boldest political innovation of the eighteenth-century Atlantic world and the document that wrote a property interest in human beings into national law (KC-3.2.II.C, KC-3.2.II.E). Third, the bookend dates do not mark clean breaks. Many of the patterns that look like Period 3 changes (party formation, religious disestablishment, westward migration) were already underway by 1754 or were not finished until well into Period 4.

Period 3 ends, in the College Board's framing, with the election of 1800. That choice is itself an argument about continuity and change. The peaceful transfer of power from the Federalists to the Democratic-Republicans was a genuine novelty in modern political history, the first time a national government changed hands between rival parties without violence (KC-3.2.III.B). The fact that it was even possible is the change. The fact that the men contesting it had been arguing with one another since the Federalist Papers and the cabinet meetings of the 1790s is the continuity. Both observations are correct, and the LEQ rewards students who hold them in tension.

The College Board names three components of the Continuity and Change reasoning process. A response that earns the analysis point on the LEQ rubric must demonstrate at least one of them in service of the larger argument; a strong response demonstrates all three. Practice each one on the eight axes listed below.

Use the table below as the anchor of the lesson. Each row asks one of the eight CED themes to do its work. The left column names the shift; the right column names what stayed. A complete LEQ response will lean on three or four rows; a comprehensive review essay can cover all eight.

How to use the table on the LEQ. A defensible thesis takes a clear position on whether change or continuity is the more consequential pattern across the chosen axis or axes, and signals which body paragraphs will carry the weight. The strongest responses argue both, with the thesis identifying which side the argument ultimately favors, and with at least one body paragraph devoted to the counterweight. A response that names only changes (or only continuities) will not earn the complexity point.

A synthesis lesson works best when its sources span the period. The three excerpts below mark the imperial moment of the mid-1750s, the constitutional founding of 1787, and the close of Period 3 at the inauguration of 1801. Read them as a set: each one anchors a different position on the continuity-change ledger.

1. (Continuity and Change · Component 3.i) Choose any one of the eight axes of change. State the pattern in a single sentence: across 1754 to 1800, in this domain, this is what shifted and this is what stayed. Defend the framing.
2. (Continuity and Change · Component 3.ii) Account for the causes of one major continuity in Period 3. Why did the institution of racial slavery survive a revolution conducted in the language of natural rights? Identify at least three contributing causes and rank them.
3. (Continuity and Change · Component 3.iii) Assess the significance of one major shift in Period 3. Was the move from monarchy to a federal republic the most consequential change of the period, or was Hamilton's financial system, or the disestablishment of state churches? Defend your ranking with evidence.
4. (Synthesis) Compare the federal Constitution of 1787 with the Articles of Confederation of 1781. The shift from one to the other is the headline change of the late 1780s. Identify two structural continuities between the documents and account for why they survived the transition.
5. (Comparison) The phrase "all men are created equal" appeared in 1776, in 1790 (Judith Sargent Murray's essay on the equality of the sexes), and in the Northwest Ordinance's antislavery provision of 1787. Trace its practical reach across these three moments. Whose status was changed by the phrase, and whose was not?
6. (Causation) Account for the global setting that made Period 3 possible. How did the French Revolution, the Haitian Revolution, the wars of the 1790s, and continued European presence in North America shape the continuity-and-change ledger inside the United States?
