Crazy Horse (Lakota: Tȟašúŋke Witkó in Standard Lakota Orthography), literally "His-Horse-Is-Crazy"; (c. 1842 – September 5, 1877) was a Native American war leader of the Oglala Lakota. He took up arms against the United States Federal government to fight against encroachments on the territories and way of life of the Lakota people, including acting as a decoy in the Fetterman Massacre and leading a war party to victory at the Battle of the Little Bighorn in June 1876.
Four months after surrendering to U.S. troops under General George Crook in May 1877, Crazy Horse was fatally wounded by a bayonet-wielding military guard, while allegedly resisting imprisonment at Camp Robinson in present-day Nebraska. He ranks among the most notable and iconic of Native American tribal members and was honored by the U.S. Postal Service in 1982 with a 13¢ Great Americans series postage stamp.
