Which legislative proposal was ultimately rejected during the Constitutional Convention that called for a single-house legislature?

The New Jersey Plan was a legislative proposal that emerged during the Constitutional Convention in 1787, advocating for a single-house legislature, or unicameral legislature. It was primarily designed to ensure that smaller states maintained equal representation in Congress, contrasting sharply with the Virginia Plan, which proposed a bicameral legislature based on population. The New Jersey Plan aimed to amend the Articles of Confederation rather than replace them entirely, emphasizing the need for a more robust federal system while preserving the sovereignty of the states.

Ultimately, the New Jersey Plan was rejected in favor of a bicameral system established by the Connecticut Compromise, which balanced the interests of both large and small states by creating a Senate with equal representation and a House of Representatives based on population. The rejection of the New Jersey Plan was significant in shaping the legislative framework of the United States Constitution, ensuring proportional representation in one chamber while granting equal representation in the other.
