Official Website


The Dakota Territory legislature created Cavalier County on January 4, 1873 with territory annexed from Pembina County, but did not organize the county government structure at that time. It was named for Charles Cavileer (or Cavalier) of Pembina (1818-1902), an early settler.

The county organization was effected on July 8, 1884. Its boundaries were altered in 1883 and in 1887.

Cavalier took its current form in 1887 after the Territorial Legislature authorized an increase in size by taking a portion from Pembina County. The expansion added 15 new townships to the county.

A site for a county seat was selected at the second meeting; it was named Langdon, for Robert Bruce Langdon of Minnesota, an official with the Great Northern Railroad. Langdon never visited the town, but reportedly donated a bell for the local school.
