General Info
Sioux County was established in 1851, organized in 1860 and named for the Sioux tribe who inhabited the area. The first settlers to the area were Joseph Bell, E.L. Stone, F.M. Hubbell and W.H. and Francis Frame. The Village of Calliope, now part of Hawarden, served as its first county seat until it was moved to Orange City in 1872 by voters. Early industry was led by agriculture as fertile soil provided ideal conditions for raising wheat, oats, corn and vegetables. Railroad expansion allowed for growth and by 1900 the population of Sioux County had reached 23,337. Today Sioux County is home to approximately 33,704 residents.
