The History of the Osage Tribe and their Wealth
The Osage Tribe, once occupying a vast territory in the United States, was forcibly relocated to southeastern Kansas. As part of the land settlement, they were promised ownership of a parcel of land in what would later become Oklahoma, along with the rights to its valuable resources, including oil, gas, coal, and other minerals.
Unbeknownst to many, the Osage Tribe experienced unprecedented wealth when oil was discovered on their land. In fact, in 1923 alone, the tribe earned over $30 million, which is equivalent to more than $400 million in today’s currency.
This newfound wealth, however, attracted the attention of the unscrupulous, making the Osage Tribe vulnerable to theft and murder.

“The wealth of the Osage Tribe was both a blessing and a curse. It brought us prosperity, but it also made us targets,” says Sarah Deer, a descendant of the Osage Tribe.
The promise of a prosperous future quickly turned into a nightmare as greed and violence became intertwined with the tribe’s newfound riches. The story of the Osage Tribe is a testament to the devastating consequences that can arise when wealth and power are concentrated in the hands of a few.
The Corruption and Crimes against the Osage Tribe
The federal government implemented a system that required some Osage individuals, deemed “incompetent,” to have a guardian oversee their finances. This resulted in widespread corruption as many guardians exploited their position to embezzle money from the Osage. Additionally, the Osage became victims of theft and murder as outsiders sought to gain control of their wealth.
The book uncovers the extent of the crimes committed against the Osage tribe, including poisonings, shootings, and bombings. The Osage were targeted simply because of their wealth and the perception that they were “incompetent” to manage it themselves.
“The corruption within the system allowed for the exploitation and victimization of the Osage tribe. Their wealth became a magnet for those looking to profit at any cost.” – David Grann, author of “Killers of the Flower Moon”

The crimes committed against the Osage tribe were not isolated incidents but instead a systematic attack on their community. The book exposes the grim reality of how corruption and greed led to the loss of innocent lives and the destruction of a once-prosperous tribe.

Edgar Hoover, in investigating the horrific acts committed against the Osage tribe.

His unwavering determination led to the eventual identification and prosecution of some of the perpetrators responsible for the killings.
“The Osage Murders cast a dark cloud over our nation, but the commitment of the FBI to bring those responsible to justice shines light on the power of relentless investigation. Through the determined efforts of Special Agent Tom White and the FBI, we are able to uncover the truth and expose the malevolence hidden within our society.”
