History
Sioux County was formed on January 15, 1851. It has been self-governed since January 20, 1860. It was named after the Sioux tribe.
The first county seat was Calliope in 1860, then a small village with 15 inhabitants, and now part of Hawarden. The first courthouse was built here in 1860 and served as such until 1872. A larger immigration wave began in 1869, primarily of Dutch. In 1872, Orange City was declared the seat. In June 1902, the construction began on a new Sioux County courthouse designed by W.W. Beach. Of red sandstone, it was completed in 1904, and still serves as the courthouse. From 1976 until 1982 the building was completely restored, and in 1977, it was listed on the National Register of Historic Places.
