Great Compromise

Updated · For the May 2027 AP exam

The Great Compromise was the Constitutional Convention's July 1787 agreement to base House seats on population and give each state two senators, settling the dispute between large and small states.

Also called
Connecticut Compromise
When
July 16, 1787

Definition

The Virginia Plan and the New Jersey Plan left the delegates deadlocked over representation, and on July 2, 1787, they split five states to five over giving each state an equal vote in the Senate. A committee then worked out a deal based on a plan from the Connecticut delegates, Roger Sherman and Oliver Ellsworth. On July 16, 1787, the Great Compromise passed by a single state, five states to four: population would decide seats in the House of Representatives, tax bills would start in the House, and every state would get two senators. State legislatures chose senators until the Seventeenth Amendment of 1913 gave that power to voters.

Why it matters on the AP exam

The compromise explains why Congress has two houses with different bases of representation, and it is the usual answer to how the Convention resolved the dispute between large and small states. Questions ask students to explain the conflict between the Virginia Plan and the New Jersey Plan and how the final structure blended both. Seats in the House based on population also forced the delegates to decide how to count enslaved people, which led to the Three-Fifths Compromise.
