Bureau of Indian Affairs
Killers of the Flower MoonThe Bureau of Indian Affairs is presented as both an instrument of federal control over the Osage and a source of records that later made the human consequences of that control more visible. Its officials enforced assimilation through compulsory schooling, while the agency’s involvement in determining who could manage money helped place Osage people under white guardians. Decades later, a handwritten guardianship register preserved a stark record of deaths among those wards.
Assimilation and Compulsory Schooling
The book places the agency’s actions within a longer history of dispossession. After the United States compelled the Osage to give up land in Kansas, settlers massacred people who had already agreed to sell their land; later, federal pressure extended beyond territory to the upbringing of Osage children. The account does not attribute these broader acts of dispossession to the Bureau alone, but it shows agency officials participating in the assimilation policy that shaped the next generation.
In 1894, when Mollie Burkhart was seven, her parents were told to enroll her at St. Louis School, a Catholic boarding institution for girls in Pawhuska. An Indian Affairs commissioner declared that Indigenous people must conform to white ways, by consent if possible and by force otherwise. Mollie’s parents were warned that refusing to send her would lead the government to withhold annuity payments, leaving the family without that support. In March, Mollie was put in a wagon and taken away from her family. The agency’s authority thus reached into the household through a direct choice between surrendering a child to compulsory schooling and risking the family’s subsistence.
Guardianship and Restricted Finances
The Bureau’s role in financial guardianship was another route by which federal policy constrained Osage autonomy. The government required the Office of Indian Affairs to determine which Osage could manage their trust funds. Despite strong opposition from the tribe, Lizzie and Anna Brown were classified as incompetent and placed under the guardianship of Scott Mathis, a prominent local white businessman who managed their finances. The arrangement reached into ordinary purchases: guardians could authorize spending down to toothpaste bought at a corner store. A World War I veteran’s complaint that he could not sign his own checks captured the contradiction between service to the country and the denial of control over one’s own money.
The classifications were not applied evenly. The book describes full-blooded Osage as routinely assigned guardians, while mixed-blood people rarely were; the determining logic was tied in practice to blood quantum. The designation converted racial identity into a restriction on property and legal agency. In 1921, Congress imposed further limits on Osage people who already had guardians: they were also classified as restricted and could withdraw only a few thousand dollars a year from their trust funds. That law was a congressional measure, not simply an agency decision, but it intensified the financial controls administered through the guardianship system. Mollie, as a full-blooded Osage, was among those whose funds were restricted; her husband, Ernest Burkhart, was her guardian.
The Register and the Record of Deaths
The agency’s paperwork, created to document guardianship, later became evidence of a pattern it had not itself resolved. While researching in the archives, the narrator found a fabric-covered Office of Indian Affairs logbook, handwritten with guardians’ names and lists of their Osage wards. When a ward died under guardianship, the clerk often added a single word beside the name: “Dead.”
The entries raised questions about deaths that had not received adequate investigation. H. G. Burt, a suspect in the killing of W. W. Vaughan, was listed as guardian of George Bigheart’s daughter and four other Osage; one ward was marked dead. Scott Mathis was listed as guardian for nine people, including Anna Brown and her mother, Lizzie. Seven of his nine listed wards had died, and at least two of those deaths were known murders. The register did not establish who was responsible for the deaths, but its repeated entries made the scale of loss difficult to dismiss.
The pattern extended beyond those two guardians. One guardian had eleven wards, eight of whom were recorded as dead; another had thirteen, with more than half deceased; another had five, all listed as having died. Because many of these cases had never been investigated, the records could not establish precisely how many deaths were suspicious or identify those responsible. The figures nevertheless appeared to defy an ordinary death rate, turning an administrative list into an indictment of how little protection the wards had received.
Allegations, Evidence, and Institutional Limits
Other records show how a death could be recorded without revealing the circumstances that might have caused it. Hlu-ah-to-me was officially said to have died of tuberculosis. A telegram from an informant to the U.S. attorney alleged that her guardian had denied her treatment and refused to send her to a hospital in the Southwest, where the informant believed she could survive. After her death, the guardian became administrator of her valuable estate. The allegation in the telegram is not presented as a finding of guilt, but it exposes the stakes of a system in which the guardian controlling a ward’s care could also gain authority over the ward’s property.
The book draws on Bureau-related documents alongside court transcripts, private investigators’ logs, Osage Tribal Council records, oral histories, and interviews with descendants. Those sources do different work: the register records administrative relationships and deaths, while family and community testimony helps recover what official files leave unresolved. The Bureau’s records therefore carry a double significance. They preserve evidence of the machinery that restricted Osage lives, yet their silences and incomplete investigations also mark the limits of what the machinery documented—or chose to pursue.
