means A late-19th-century Native American spiritual movement and ceremonial round dance, led by believers that performing it would restore ancestors, buffalo, and the old world while making the invading settlers disappear.

from The movement traces to a Northern Paiute spiritual leader named Wovoka, who in 1889 reported a vision during a solar eclipse instructing people to dance a circling, trance-inducing round dance to hasten a coming renewal of the earth. The practice, and the name 'Ghost Dance' (translating a Paiute term tied to the dead returning), spread rapidly among Plains nations including the Lakota, who adapted it amid the desperation of reservation life, broken treaties, and the loss of the buffalo. U.S. authorities, alarmed by its spread and misreading it as a prelude to uprising, moved to suppress it — a fear that culminated in the 1890 massacre at Wounded Knee.
