Further details:
The Connecticut Compromise was a measure decided during the United States Constitutional Convention in 1787. Also known as "The Great Compromise," it resolved a dispute between small population states and large population states. It was important because it created a two-chamber legislature, with proportional representation in the House and equal representation for all states in the Senate.
The large population states wanted representation in Congress to be based on a state's population size. (This was the essence of the Virginia Plan.) The smaller states feared this would lead to unchecked dominance by the big states; they wanted all states to receive the same amount of representation. (This was the New Jersey Plan.)
The Great Compromise (aka Connecticut Compromise) created a bicameral (two-chamber) legislature, with different rules for representation in each chamber. Representation in the House of Representatives would be based on population. In the Senate, all states would have the same amount of representation, by two Senators.
