The Treaty of Fort Harmar was an agreement between the United States government and numerous Native American tribes with claims to what post-AMerican revolutionary War territory northwest of the River Ohio, and that legally existed from July 13 1787 until March 1, 1803?
Northwest Territory The post-American Revolutionary War Territory Northwest of the River Ohio, more commonly known as the Northwest Territory encompassing most of the pre-war territory of the Ohio Country, parts of Illinois Country, and parts of old French Canada below the Great Lakes was an organized incorporated territory of the United States spanning most or large parts of six eventual U.S. States. It existed legally from July 13, 1787, until March 1, 1803, when the southeastern portion of the territory was admitted to the Union as the state of Ohio, and the remainder was reorganized by additional legislative actions.
Tecumseh's War Tecumseh's War or Tecumseh's Rebellion was a conflict between the United States Army and an American Indian confederacy led by the Shawnee leader Tecumseh in the Indiana Territory. Although the war is often considered to have climaxed with William Henry Harrison's victory at the Battle of Tippecanoe in 1811, Tecumseh's War essentially continued into the War of 1812, and is frequently considered a part of that larger struggle. The war lasted for two more years, until the fall of 1813, when Tecumseh, as well as second-in-command Roundhead died fighting Harrison's Army of the Northwest at the Battle of the Thames in Upper Canada, near present-day Chatham, Ontario, and his confederacy disintegrated. Tecumseh's War is viewed by some academic historians as being the final conflict of a longer term military struggle for control of the Great Lakes region of North America, encompassing a number of wars over several generations, referred to as the Sixty Years' War.
