Allotments could be sold after a statutory period (25 years), and "surplus" land not allotted was opened to settlers. Within decades following the passage of the act the vast majority of what had been tribal land in the West was in white hands.
The act also established a trust fund to collect and distribute proceeds from oil, mineral, timber, and grazing leases on Native American lands. The failure of the Bureau of Indian Affairs to manage this trust fund properly led to legislation and lawsuits in the 1990s and early 2000s to force the government to properly account for the revenues collected.
