Who was the principal drafter of the United States Constitution’s Virginia Plan?

James Madison was the principal drafter of the Virginia Plan presented at the Constitutional Convention.

Madison prepared the plan before the convention opened in Philadelphia in 1787. It proposed a stronger national government with separate legislative, executive, and judicial branches. Its legislature would have two chambers, and representation would be based on population or financial contributions rather than giving every state an identical vote.

Virginia Governor Edmund Randolph formally presented the plan to the convention on May 29, 1787, so it is often called the Randolph Plan as well as the Virginia Plan. Madison’s notes and preparation were crucial to its development, and he became one of the convention’s most influential participants.

The convention did not adopt the plan exactly. Its ideas shaped later debates, including the Great Compromise, which created a House based on population and a Senate with equal representation for each state.
