Excerpt from the article…

The treaty making process between the Indian nations and the United States of America was stopped shortly after the huge treaty meeting that took place at Fort Laramie in 1868. Several Indian nations were on hand to “negotiate” the treaties that became known throughout Indian country as The Fort Laramie Treaty of 1868.
Representatives of the several tribes of the Great Sioux Nation were there to negotiate away millions of acres of land, but were they “duly authorized” representatives? Tasunka Witko (Crazy Horse) and his followers were not present. Crazy Horse, in his short lifetime, never touched a pen to a treaty.
