Which 1787 compromise created equal representation for every state in the United States Senate?

The Connecticut Compromise created equal representation for every state in the United States Senate.

Agreed at the Constitutional Convention in July 1787, the Connecticut Compromise established a bicameral Congress with different representation rules. The House of Representatives would be based on state population, while every state would have two senators. This structure balanced the demands of large and small states.

Roger Sherman and Oliver Ellsworth of Connecticut were important advocates of the arrangement, which is also widely called the Great Compromise. Without it, the convention might not have resolved the dispute over whether states or population should determine legislative power.

The compromise did not make both chambers identical. Revenue bills had to begin in the House, and the Senate received special responsibilities such as confirming appointments and approving treaties. It is distinct from the Three-Fifths Compromise, which addressed representation and taxation involving enslaved people.
