Originally published in a House Executive Document, this map presents names and locations of Native American reservation land within the United States at the end of the 19th century. It belongs to a series of Indian Affairs Commissioner maps published and updated in the 1890s and early 1900s. The cartography, of course, was far from benign, as the federal government used these maps in its efforts to acquire and open Indian reservation land, for example with the Oklahoma Land Run of 1891.
It is no surprise then that Oklahoma is given a featured inset with extra detail. Two other insets include Alaska and a close-up of Mission Indian Reservation in southern California.
