What Treaty that ended the American Revolutionary war made George Rogers Clark hailed as  the "Conqueror of the Old Northwest"?
George Rogers Clark George Rogers Clark (November 19, 1752 – February 13, 1818) was a surveyor, soldier, and militia officer from Virginia who became the highest ranking American military officer on the northwestern frontier during the American Revolutionary War. He served as leader of the militia in Kentucky (then part of Virginia) throughout much of the war. Clark is best known for his celebrated captures of Kaskaskia (1778) and Vincennes (1779) 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".
Treaty of Surat The Treaty of Surat (6 March 1776) was a treaty by which Raghunathrao, one of the claimants to the throne of the Peshwa, agreed to cede Salsette and Bassein Fort to the English, in consideration of being himself restored to Poona. The military operations that followed are known as the First Anglo-Maratha War. Warren Hastings, who in his capacity of Governor General claimed a right of control over the decisions of the Bombay Government, annulled the Treaty of Surat and sent his own agent to negotiate a very different new pact, the Treaty of Purandhar (1776).
