It appears that both Young Man Afraid of His Horses and
his father signed the Treaty of Fort Laramie of 1868 which ended Red Cloud's War,
but they had no intention of leaving their Powder River hunting grounds to permanently settle on the Great Sioux Reservation, at least initially.
When they occupied the village of Wounded Knee on the Pine Ridge Lakota Sioux Reservation in February 1973, the AIM and
their local allies demanded that the government reinstate the 1868 Fort Laramie Treaty, which had granted to the Sioux Nation
much of the territories of the current states of Montana, Wyoming, North and South Dakota and Nebraska.
