What is "dohasan"

Dohäsan, Dohosan, Tauhawsin, Tohausen, or Touhason (late 1780s to early 1790s – 1866) was a prominent Native American. He was War Chief of the Kata or Arikara band of the Kiowa Indians, and then Principal Chief of the entire Kiowa Tribe, a position he held for an extraordinary 33 years. He is best remembered as the last undisputed Principal Chief of the Kiowa people before the Reservation Era, and the battlefield leader of the Plains Tribes in the largest battle ever fought between the Plains tribes and the United States.
