On December 15, 1791, Virginia became the eleventh state to ratify the first ten amendments to the U.S. Constitution, meeting the three-fourths threshold required for adoption. Originally twelve amendments were proposed by Congress on September 25, 1789, drafted primarily by James Madison. The ratified ten addressed individual liberties including speech, assembly, and petition rights, protections against unreasonable searches, and guarantees of due process. The amendments responded to Anti-Federalist concerns that the original Constitution lacked explicit protections for individual rights.
