What made Crazy Horse famous?

Crazy Horse became famous because he was a steadfast and ferocious warrior. However, he stayed famous because he defended his culture, becoming a leader for his people.

According to PBS, by the time he was out of his teens, he was already a celebrated warrior of the Lakota people. He defended his people by refusing to let Europeans take over the land, and he defended his culture by denying European infringements on the Lakota culture, such as photography. He led the rebellion against the troops trying to force the Lakota onto reservation land, fighting against General Custer and General Nelson Mills along the way. He eventually surrendered to the troops, however. Though he ended up on the reservation, he was killed by troops as he tried to take his wife to her family.
