Blue County was a political subdivision of the Choctaw Nation of Indian Territory, prior to Oklahoma being admitted as a state.
[3] Prior to being known as Blue County, the area was called Tiger Spring County—or Koi Kulih Kaunti in Choctaw.
[6] The county served as an election district for members of the National Council, and as a unit of local administration.
Constitutional officers, all of whom served for two-year terms and were elected by the voters, included the county judge, sheriff, and a ranger.
The sheriff collected taxes, monitored unlawful intrusion by intruders (usually white Americans from the United States), and conducted the census.
While this was not generally true of Blue County, with its bustling commercial towns of Caddo and Durant, it would have to be dismantled in order to accommodate changes required by the region at large.
