Sherman served as a delegate to the 1787 Philadelphia Convention, which produced the United States Constitution. After Benjamin Franklin, he was the oldest delegate present at the convention. He favored granting the federal government power to raise revenue and regulate commerce, but initially opposed efforts to supplant the Articles of Confederation with a new constitution. He ultimately came to support the establishment of a new constitution, and proposed the Connecticut Compromise, which won the approval of both the larger states and the smaller states.
