George Rogers Clark was a surveyor, soldier, and militia officer from Virginia and the highest ranking American military officer on the northwestern frontier during the American Revolutionary War. He served as leader of the Kentucky militia throughout much of the war. Clark is best known for his celebrated captures of Kaskaskia and Vincennes during the Illinois Campaign, which greatly weakened British influence in the Northwest Territory. Because the British ceded the entire Northwest Territory to the United States in the 1783 Treaty of Paris, Clark has often been hailed as the Conqueror of the Old Northwest.
George Rogers Clark was born on November 19, 1752 in Charlottesville, Virginia, near the home of Thomas Jefferson. He was the second of ten children of John Clark and Ann Rogers Clark, who were Anglicans of English and Scots ancestry. Five of their six sons became officers during the American Revolutionary War. Their youngest son, William Clark, was too young to fight in the Revolution, but later became famous as a leader of the Lewis and Clark Expedition. In about 1756, after the outbreak of the French and Indian War , the family moved away from the frontier to Caroline County, Virginia, and lived on a 400acre plantation that later grew to over 2,000 acres .
