United States Department of the Interior
Killers of the Flower MoonThe United States Department of the Interior appears in the history of the Osage Nation at the point where federal administration met the tribe’s mineral wealth: the department oversaw oil-lease auctions, while the wider federal guardianship system subjected many Osage property holders to outside control. The book distinguishes these specific administrative roles from broader actions by the United States government and Congress. Together, they show how retained ownership of underground resources could coexist with severe restrictions on the people whose land and headrights generated the wealth.
Federal Administration and Osage Land
The department’s place in this history belongs to a longer period of federal pressure on Osage land and political autonomy. After the United States compelled the Osage to relinquish territory between the Arkansas River and the Missouri River, the tribe was forced to cede nearly a hundred million acres over the following decades and eventually found refuge in a 50-by-125-mile area in southeastern Kansas. In 1870, after being expelled from their lodges and seeing graves plundered, the Osage agreed to sell their Kansas lands to settlers for $1.25 an acre; settlers nevertheless massacred several Osage people. These episodes are described as actions of the government, settlers, and federal agents, not attributed specifically to the United States Department of the Interior.
In the late nineteenth century, the federal allotment campaign proposed dividing the Osage reservation into individual 160-acre parcels and opening the remaining territory to settlers. The policy aimed to replace communal landholding with private property, a change that would also make Indigenous land easier to acquire. The Osage delayed allotment longer than any other tribe in Indian Territory and negotiated more favorable terms: land was divided among tribal members, increasing each allotment to 657 acres, while the agreement reserved oil, gas, coal, and other minerals to the Osage Tribe. The account describes negotiations with government officials but does not identify the department as their sole or principal negotiator. The distinction matters: the mineral reservation preserved a collective resource even as allotment transformed the land above it.
Mineral Rights and the Lease Auctions
The department’s clearest direct role was its oversight of Osage oil-lease auctions. Held about four times a year, the auctions offered leases to drill on portions of the tribe’s underground reservation. Since the auctions began in 1912, only part of the extensive mineral estate had been opened to drilling, and bids for a single lease—typically covering a 160-acre tract—rose dramatically. The department’s oversight placed it at the administrative center of a process through which companies and independent oilmen competed for access to resources the Osage had reserved in the allotment agreement.
The auctions drew major oil operators to Pawhuska, capital of the Osage Nation, in luxurious private railcars. In good weather, bidding took place outdoors on a hill beneath the Million Dollar Elm, with Osage people and local settlers among the spectators. The bidding was risky for small operators: a successful lease could make a penniless wildcatter rich, while a mistaken bid could ruin him. Oilmen studied geological maps and sought information from employees and spies; the wealth at stake extended beyond individual fortunes into national politics. Sinclair, E. W. Marland, and other oilmen helped finance Warren Harding’s successful presidential campaign. The account describes the subsequent federal leasing of naval oil reserves as part of the Teapot Dome scandal, a related instance of political influence over petroleum resources, not as an Osage lease auction run by the department.
Guardianship and Restricted Access to Wealth
A second important connection to the department was its role in determining which American Indians were deemed incompetent and therefore required to have financial guardians. In practice, the designation was closely tied to blood quantum: full-blooded Osage people were invariably assigned guardians, while mixed-blood people rarely were. The rule converted racial classification into different levels of control over property. John Palmer, an Osage attorney who had helped secure the tribe’s mineral rights, argued before Congress that blood quantum should not determine how much control officials took over tribal members’ money, but his appeal was ignored.
The system reached into ordinary spending. At a 1920 House subcommittee hearing, lawmakers scrutinized an inspector’s report on Osage expenditures, including a $319.05 butcher-shop bill incurred by Lizzie before her death. The detail illustrates the disparity between federal attention to individual Osage purchases and the limited autonomy allowed to people whose finances were administered by guardians. The book also describes guardians who used their positions to inflate prices, steer business for kickbacks, purchase property for themselves, or steal outright. One guardian bought a car for $250 and resold it to his ward for $1,250. A government study estimated that guardians had directly pilfered at least $8 million from restricted Osage accounts before 1925. Those abuses implicate a broader network of guardians, businessmen, lawyers, politicians, and local officials; the evidence does not establish that the department itself directed each fraud.
In 1921, Congress added further restrictions. Osage people who had guardians were also classified as restricted, limiting them to withdrawing only a few thousand dollars a year from their trust funds, even when money was needed for education or a child’s hospital care. The law left guardians in place and narrowed their wards’ access to their own funds. Mollie Burkhart, a full-blooded Osage woman, was among those whose money was restricted; her husband, Ernest Burkhart, served as her guardian. This restriction is attributed to Congress, while the department’s documented role in the larger system includes determining incompetency and administering the auctions.
Institutional Power and Its Limits
The department’s two documented roles expose a central contrast in the Osage experience. Federal administration helped stage access to the tribe’s oil through recurring lease auctions, while federal classifications and financial rules constrained many Osage people’s ability to manage the proceeds associated with their property. The tribe’s negotiated mineral reservation protected an underground estate from being divided with the surface allotments, but it did not protect every individual headright holder from guardianship, restricted withdrawals, or predatory local dealings.
The account therefore presents the United States Department of the Interior neither as the sole author of the policies affecting the Osage nor as a neutral bystander. It identifies the department’s concrete authority over leasing and its place in the guardianship apparatus, while assigning other decisions—such as allotment terms and the 1921 withdrawal restrictions—to negotiations with government officials or to Congress. That distinction clarifies how power operated: through separate legal and administrative channels that governed land, leases, classifications, and access to money, even as the Osage had secured an important collective claim to the minerals beneath their reservation.
