Texas, Jack County has a rich frontier and ranching history.
Jack County was created from Cooke County in 1856. The first court met on 22 July 1857 in the front yard of T.S. Nettles at Mesquiteville in the Salt Creek community, two miles south of the present courthouse square. The Butterfield Stage Route or Upper California Road and Southern Overland Mail route ran through Jack County until the beginning of the Civil War. The location of the mail route is easily found in the county. The county seat was moved to the present location and the name changed in 1870 to Jacksborough. In 1867, Fort Richardson was established as one of the second line of defense forts against the Indians. From 1875-1876, the Mooar Brothers' buffalo trail led thorugh Fort Richardson and the Old Emigrant Trail passed through Jack County, traveling from Gainesville to Fort Griffin. The county seat became known as Jacksboro in 1874.
