Pride of place within the historiography of Indian Territory and early Oklahoma probably belongs to Angie Debo, who in this 1940 book exposed how unscrupulous businessmen victimized the most prominent victims of Indian Removal, the Five Civilized Tribes. Between 1906 and 1908, Oklahoma statehood and the passage of federal and state land-allotment acts licensed white entrepreneurs to descend on the Cherokees, Chickasaws, Choctaws, Creeks, and Seminoles, and cheat them of their resources. The next two decades witnessed “an orgy of plunder and exploitation” (p. 91) in eastern Oklahoma. Private firms and individual speculators persuaded Native American heads-of-household or local judges to give them power of attorney over uneducated Indians' property. Courts made enterprising whites the guardians of newly-wealthy Indian minors. Real-estate offices hosted weddings (usually in name only) between female allottees and white grifters. Attorneys devised exploitative contracts that bought Indian communities' resources for a song. When all else failed, con men resorted to forgery, fraud, and even murder to obtain Oklahoma Indians' land, timber, and oil.
As with Indian Removal two generations earlier, this campaign of land-piracy occurred under the aegis of American law, and its magnitude nearly overwhelmed Oklahoma's judicial system. Tens of thousands of Indian-related civil cases clogged state courts into the 1920s, and county judges used their influence and issuance of guardianships to build personal political machines. They and state officials fought private businessmen in the 1930s for shares of the spoils, while the Native families they had despoiled struggled with famine and poverty in a land of natural plenty (p. 356). Debo's study has an old-fashioned feel to it, insofar as it presents Native Americans as passive victims of white greed and focuses on the plunderers. But her thorough research and pitiless explication of whites' greed and exploitation make her book a classic, and set a high standard for future histories of Indian-white relations in the Sooner State.
