After the
American Revolutionary War established US sovereignty over the territory of the upper midwest, the new federal government defined the
Northwest Territory in 1787, which included the area of present-day Indiana. In 1800, Congress separated Ohio from the Northwest Territory, designating the rest of the land as the Indiana Territory. President Thomas Jefferson chose William Henry Harrison as the governor of the territory, and Vincennes was established as the capital. After the Michigan Territory was separated and the Illinois Territory was formed, Indiana was reduced to its current size and geography. By December 1816 the Indiana Territory was admitted to the Union as a state. The
Native people who inhabited these areas prior to arrival of European settlers were generally resistant to the loss of their lands. As settlers pushed into the area, treaties signed by some leaders with United States representatives ceded large areas of their territory to the US. Starting in 1794, Native American titles to Indiana lands were extinguished by usurpation, purchase, or war and treaty. The United States acquired land from the Native Americans in the
1809 treaty of Fort Wayne, and by the
treaty of St. Mary's in 1818, which included the future Shelby County. The Indiana State Legislature passed a bill on December 31, 1821, that authorized the creation of four counties, including Shelby. On July 1, 1822, the county was organized, beginning with selecting a site for the county seat. The new county was named for Gen.
Isaac Shelby, who defeated the British at the
Battle of Kings Mountain in the
Revolutionary War. Shelby then became the first
Governor of Kentucky. During the
War of 1812, he led the army of Kentucky into
Canada, and defeated the British at the decisive
Battle of the Thames in 1813. ==Geography==
