Wavoka was a religious leader who founded the second episode of the Ghost Dance movement. The Ghost Dance movement was a spiritual movement that came about because of multiple visions of an elder, Wodziwob. The vision were about the renewal of Earth and help for the Paiute people as promised by their ancestors. Wavoka's prophecy of an end to white expansion was associated to the ghost dance and its goals were to promote clean living, an honest life, and cross-cultural cooperation by the Indians and thats why it became so popular.
The Wounded Knee Massacre was a domestic massacre of around 300 Lakota people, by the US Army. It was passed off as a battle but was really a tragic and avoidable massacre. The Wounded Knee Massacre marked the end of Indian resistance to the encroachment of white settlers.
