The town was founded in 1883 by a group of white settlers who had arrived in Choctaw Nation, Indian Territory in 1882 from Gainesville, Texas, led by Confederate Army veteran Doctor John Trigg Gilmore, his wife, Elizabeth Louise Oliveaux, their children, and relatives William and George McCall, with their respective families. They first settled in Cold Springs, northwest of the present town site, where other settlers soon joined them. The first log cabin was built in Allen in 1883, and this building was used as both a school and church. The town was named after the son of deputy United States marshal William McCall.
Allen, Oklahoma is the modern-day site of the Battle of Middle Boggy during the American Civil War.
