Video: '29th December 1890: Lakota Sioux massacred at Wounded Knee'

(Monday, December 29, 1890, morning local time; during the Wounded Knee Massacre, part of the Ghost Dance War and the Sioux Wars and the American Indian Wars) — Nearly 300 Lakota men, women, and children were massacred by soldiers of the United States Army today near Wounded Knee Creek on the Lakota Pine Ridge Indian Reservation in South Dakota. 25 soldiers also died.

The massacre followed a botched attempt by U.S. 7th Cavalry Regiment — the reconstructed regiment lost by George Armstrong Custer — to disperse the non-violent “Ghost-Dance” which was promised to usher in a new era of power and freedom to Native Americans but was feared as a potential rallying tool for violent rebellion by some in the U.S. government.

This was the last tribe to be defeated and confined to a reservation as well as the beginning of the decline of both the American Indian Wars and the American frontier.

In 1990, both houses of the U.S. Congress passed a resolution on the historical centennial formally expressing “deep regret” for the massacre.
