(1750–1818) Revolutionary War army officer. A Virginian, as the Revolution approached Posey served on the Botetourt County committee of correspondence, and he became a company commander in the Continental army. He fought at Saratoga (1777) and was present at Yorktown (1781). After the war he resigned his commission but returned to military service in 1793, serving in the Northwest Territory. After an unsuccessful run for the U.S. House of Representatives (1797), he moved to Kentucky, where he won election to several state offices. Unsuccessful in business, he relocated to Baton Rouge, Louisiana, where in 1812 he filled a recess appointment to the U.S. Senate. In 1813 he was named governor of the Indiana Territory; he opposed statehood and, after Indiana joined the Union as a state in 1816, was defeated in the election for the state's first governor.
