Wounded Knee Massacre
29 Dec 1890
Causes: The US banned the Indian Sun Dance in 1884 to get Indians to give up their tribal religions and assimilate. Instead, the "Ghost Dance" spread in order to resist assimilation under the Dawes Severalty Act.
People: Dakota Sioux, US Cavalry
Effects: The US army killed around 200 Indians, including women and children, and practice of the Ghost Dance dropped hugely out of fear.
