Which plan proposed a unicameral legislature with equal representation for each state?

The New Jersey Plan proposed a unicameral legislature in which each state would have equal representation. This plan arose in response to the Virginia Plan, which favored larger states by suggesting a bicameral legislature with representation based on population. The New Jersey Plan aimed to protect the interests of smaller states by ensuring that every state had the same number of representatives, thus preventing larger states from dominating the legislative process.

This equal representation was designed to maintain a balance of power among the states in the new national government structure. The significance of the New Jersey Plan ultimately influenced the discussions at the Constitutional Convention, particularly in the compromise that led to the establishment of a bicameral legislature with both equal representation in the Senate and proportional representation in the House of Representatives, known as the Connecticut Plan or the Great Compromise.
