This is one page from the Final Rolls of Citizens and Freedmen of the Five Civilized Tribes in Indian Territory, published on March 4, 1907. It records individual roll numbers and other pertinent information. The Federal Government used these registers to distribute 138 million acres of tribal land. After apportioning more than 50 million acres to Native Americans, the Government made the rest available to non-native peoples for settlement.
