He presided at the convention that drafted the United States Constitution. Washington has been called the \"Father of His Country\" for his manifold leadership in the formative days of the new nation. Born into a prominent family in colonial Virginia, Washington was a planter who grew tobacco and wheat on his Mount Vernon estate. He became a successful land speculator and surveyor, leading him to the colonial militia and ultimately to the Virginia House of Burgesses. He led Virginia forces to victory in the French and Indian War (1754–1763), and was later elected to the Continental Congress, where he became a leading spokesman for the Patriot cause in the American Revolution. He was elected President of the Constitutional Convention in 1787, which drafted the Constitution and established the federal government. He was unanimously elected as the first President of the United States in 1789, and served two terms, presiding over the establishment of the nation's financial system, its capital city, and a strong national army. He has been ranked both by scholars and the public as the greatest U.S. president, and was the first president to be memorialized on Mount Rushmore. Washington was born on February 22, 1732, on Pope's Creek in Westmoreland County, Virginia, to Augustine Washington (1694–1743) and his second wife, Mary Ball Washington (1708–1789). Augustine was a planter who grew tobacco and wheat on his large estate, Wakefield, in the Northern Neck region of Virginia. He also served as a justice of the county court, and, as a member of the House of Burgesses, helped draft legislation to establish religious freedom in Virginia. He was the son of Augustine Washington (1656–1729
