Wesley Bad Heart Bull was a Native American man whose death served as one of the catalysts for the Occupation of Wounded Knee. When Wesley Bad Heart Bull was killed by a white man, American Indian Movement (AIM) activists gathered at the courthouse where his killer would be tried. After discovering that Wesley’s murderer would only be charged with second-degree manslaughter, the AIM activists began to riot, after which Oglala Sioux Civil Rights Organization (OSCRO) activists asked them for help in protesting Wilson’s violent regime. It was when AIM activists joined up with OSCRO activists to plan a demonstration that they decided to occupy Wounded Knee.
