Fort Riley is named in honor of Major General Bennett C. Riley who led the first military escort along the Santa Fe Trail. The fort was established in 1853 as a military post to protect the movement of people and trade over the Oregon, California, and Santa Fe trails. In the years after the Civil War, Fort Riley served as a major United States Cavalry post and school for cavalry tactics and practice. The post was a base for skirmishes with Native Americans after the Civil War ended in 1865, during which time George Custer was stationed at the fort.
