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 Treaty of Grouseland (1805), by which a large portion of the southern Indiana Territory became property of the government. This included the future Washington County. As early as 1802, a man named Frederick Royce lived among the Ox Indians at a place known as the Lick, two miles east of Salem and is probably the first white man to inhabit this county. He was a hunter-trader and salt manufacturer. In 1803, Thomas Hopper settled in this county near Hardinsburg. Washington County was created by act of the Territorial legislature dated 21 December 1813, taking territory from Harrison and Clark counties. Interim commissioners were named and directed to determine the proper choice of the seat of government. Accordingly, they began deliberating in January 1814, and by 2 February had selected an uninhabited site near the center, naming it 'Salem'. In the territorial act creating the county, it was named for U.S. President George Washington, who had died fourteen years earlier.
