James Madison drew on the Magna Carta, the English Bill of Rights, and Virginia’s Declaration of Rights, mainly written by George Mason, in drafting 19 amendments, which he submitted to the U.S. House of Representatives on June 8, 1789. The House approved 17 of them and sent it to the U.S. Senate, which approved 12 of them on September 25. Ten were ratified by the states and became law on December 15, 1791.
