The Lakota Sioux Indians of the Great Plains possess rich religious traditions which are tied closely to the Earth. Though the relegation of these people to reservations amid the environmental disasters of American development has resulted in the near destruction of an ancient culture, some Lakota Sioux continue to fight for the preservation of their sacred lands animals, civil rights, and way of life.The seven original bands of the Great Sioux Nation were joined in an alliance called the Seven Council Fires.
