Great (Connecticut) Compromise in AP US Government

The Great (Connecticut) Compromise was the 1787 Constitutional Convention agreement that created a bicameral (two-chamber) Congress, with House of Representatives seats based on each state's population and equal representation for every state in the Senate. It blended the large states' Virginia Plan with the small states' New Jersey Plan, and it settled the biggest dispute at the Convention.

Two chambers, two different answers to who gets represented

The dispute was about power in the new legislature. Large states like Virginia wanted representation by population, since more people should mean more votes. Small states like New Jersey and Delaware wanted one state, one vote, which is how Congress already worked under the Articles of Confederation.

Connecticut delegates Roger Sherman and Oliver Ellsworth pushed a split. The House would represent people, with seats apportioned by population and recounted through a census every ten years. The Senate would represent states, with two senators each no matter the state's size.

This term belongs to Topic 1.5, Ratification of the U.S. Constitution, in Unit 1: Foundations of American Democracy. The course uses it to show how bargaining at the Convention shaped the system we have. The Great Compromise is the clearest case, because the structure of Congress itself is the bargain.

Where the bargain still shows up in the Constitution's text

The compromise left fingerprints in several clauses, and naming them makes an answer stronger than just saying "Congress has two houses."

  • Revenue bills must start in the population-based House, a concession to large states, though the Senate still has to approve them.
  • Senators were originally chosen by state legislatures, which reinforced the idea that the Senate speaks for states. The 17th Amendment (1913) switched to direct election.
  • Article V protects the deal by saying no state can lose its equal vote in the Senate without its own consent, which makes Senate equality nearly impossible to amend away.

The bicameral design also connects to Federalist 51, a required document. Madison argues there that dividing the legislature into different branches helps keep any one part of government from becoming too powerful. That links the compromise to checks and balances, which makes it useful evidence in essays about limiting power.

What the Connecticut deal left unsettled

The compromise decided how Congress is structured. It didn't decide who counts as population for House seats. That question, about enslaved people, needed a separate deal, the Three-Fifths Compromise.

It also created a gap that grows as populations shift. Today California, with roughly 39 million people, and Wyoming, with fewer than 600,000, each get two senators. Critics call this undemocratic. Defenders say it protects smaller states and fits federalism. This matches the course's point that compromises needed for ratification left some questions open, and those questions are still argued over now.

One more limit is that the deal says nothing about how the president is chosen. That was handled by the Electoral College, though that plan borrowed the same math, since each state's electors equal its House seats plus its two senators.

Writing about it in Concept Application and the Argument Essay

A table listing state populations next to House and Senate seats could show up as a stimulus, where you'd explain why the Senate numbers don't track population. A text stimulus, like a delegate's quote or a passage from a founding document, might instead ask you to identify the plan or compromise being described. Other multiple-choice items ask which Convention dispute the compromise resolved.

On Question 1 (Concept Application), a scenario might describe a bill passing the House but stalling in a Senate where small-state senators hold the votes. A top answer names the Great Compromise as the reason the chambers represent different things and then explains the effect on lawmaking.

On Question 4 (Argument Essay), the compromise works as reasoning for a thesis about how the Constitution balanced competing interests or limited power. Pair it with Federalist 51's case for dividing the legislature. For an opposing view, use the Senate's unequal weight per citizen, then rebut by pointing to federalism and the protection of small-state interests.

Keeping it separate from the Three-Fifths and Electoral College deals

Wrong answers often swap in a different 1787 compromise, so tie each to the exact problem it solved. The Great Compromise settled the structure of Congress. The Three-Fifths Compromise settled how enslaved people were counted for House seats and taxes. The Electoral College settled how the president is chosen instead of by popular vote or Congress. The Compromise on the Importation of Slaves prevented Congress from banning the importation of enslaved persons before 1808.

A second slip is giving the whole design to one plan. The Virginia Plan supplied population-based representation and the New Jersey Plan supplied equal state votes. The compromise kept a piece of each, one per chamber, so be ready to say which chamber came from which idea.
