When drafting the constitution, delegates argued about how to keep the most populated states from gaining too much power. finally, they came up with the which created two legislative houses (senate and house of representatives). the senate provides equal representation to each state, and the house of representatives is based on population?

The Connecticut Compromise (aka The Great Compromise)

This compromise was a combination of The New Jersey Plan (one legislative house with equal representation from each state) and The Virginia Plan (two houses with representation based on population for both houses).

The founding fathers made the Great Compromise and ratified a bicameral legislature with one houses representation based on population (House of Representatives) and the other house having equal representation from each state (Senate).
