Crowfoot (1830 – 25 April 1890) or Isapo-Muxika (Blackfoot Issapóómahksika, "Crow-big-foot") was a chief of the Siksika First Nation. His parents, Istowun-eh'pata (Packs a Knife) and Axkahp-say-pi (Attacked Towards Home), were Kainai. He was only five when Istowun-eh'pata was killed during a raid on the Crow tribe, and a year later, his mother remarried to Akay-nehka-simi (Many Names) of the Siksika people where he was brought up.
