At the tender age of 13, this legendary warrior was stealing horses from neighboring tribes. By the time he was 20, Crazy Horse was leading his first war party under the instruction of Chief Red Cloud. The Lakota warrior spent his life fighting for the preservation of his people's way of life. He amassed more than 1,200 warriors to help Sitting Bull defeat General Crook in 1876. After that, Sitting Bull and Crazy Horse joined forces, eventually defeating Custer at Little Bighorn. Crazy Horse continued to tirelessly defend his people's rights, but by 1877, there was little fight left in him. When trying to get to his sick wife, Crazy Horse was killed with a bayonet.
