 In 1819 the State of Alabama was admitted to the Union and was soon organized into counties.The county that Troy was eventually founded in, known as Pike County, was one of the first counties established in Alabama.It comprised a large tract of country, so large that it was called the "State of Pike", which included parts of what are now Crenshaw, Montgomery, Macon, Bullock, and Barbour counties, and extended to the Chattahoochee River on the east.
