COUNTY FORMATION
Knox County was created in January 13, 1825. It was one of ten counties carved from a large section of military tract. "East from the fourth principal meridian on the line between towns 8 and 9 north, to the line between ranges 4 and 5 east; thence north to the line between towns 12 and 13 north; thence west to the fourth principal meridian; thence south to the beginning." Previously, since 1823, it fell in Fulton county's boundaries. In 1821 it became a portion of Pike County. From 1812 to 1820 the land was part of Madison county.
Knox county was named in honor of Revolutionary War General Henry Knox, who is known as the father of the American army artillery.
