Final answer:
James Madison supported the Great Compromise during the Constitutional Convention of 1787.
Step-by-step explanation:
James Madison supported the Great Compromise. The Great Compromise, also known as the Connecticut Compromise, was a solution reached during the Constitutional Convention of 1787 to resolve the disagreement between small and large states on the representation issue. The compromise proposed a bicameral legislature, with one house (the House of Representatives) based on population and the other house (the Senate) giving equal representation to each state. James Madison, along with other founding fathers such as Thomas Jefferson, recognized the importance of compromise in creating a strong and lasting union.
