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.
List of U.S. state partition proposals Since the establishment of the United States in 1776, numerous state partition proposals have been put forward that would either set-off a portion of an existing state (or states) in order that this region might either join another state or create a new state. Article IV, Section 3, of the United States Constitution, oftentimes called the New States Clause, grants to the United States Congress the authority to admit new states into the United States beyond the thirteen already in existence at the time the Constitution went into effect (June 21, 1788, after ratification by nine of the thirteen states). It also includes a stipulation originally designed to give Eastern states that still had Western land claims (then including Virginia, North Carolina, and Georgia) a veto over whether their western counties could become states.
