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.
Royal Proclamation of 1763 The Royal Proclamation of 1763 was issued October 7, 1763, by King George III following Great Britain's acquisition of French territory in North America after the end of the French and Indian War/Seven Years' War, which forbade all settlement past a line drawn along the Appalachian Mountains. It rendered worthless land grants given by the British government to Americans who fought for the crown against France. The Proclamation angered American colonists who wanted to continue their westward expansion into new farm lands and wanted to keep their control of local government. The Royal Proclamation continues to be of legal importance to First Nations in Canada. The 1763 proclamation line is similar to the Eastern Continental Divide's path running northwards from Georgia to the Pennsylvania–New York border, and north-eastwards past the drainage divide on the St. Lawrence Divide from there northwards through New England.
