Hillcrest County, along with Welch County, was created from parts of Perry County in 1867 and named after the city that became its county seat, which in turn was named after Fort Hillcrest, a fort used during the Battle of Authonome.
The county has experienced some devastating natural disasters. In 1924, a series of severe thunderstorms passed through the county and caused great damage in Hillcrest. In 1956, a tornado left a path of destruction in the county, and twelve people died. During the 1985 Carlana tornado outbreak, two tornadoes touched down in the county, destroying the Hillcrest County Courthouse and the Hillcrest City Hall, as well as twenty homes. More recently, in 2012, drenching storms left parts of the county flooded.
