The Japan Times - Scorsese 'Flower Moon' epic based on real Native American past

Ahead of the movie's US release, AFP looks at the real-life story behind the film, which was adapted from US author David Grann's 2017 book of the same name.

- Who are the Osage? -

The Osage, a Native American nation which grew out of the Ohio and Mississippi River valleys, was forcibly relocated by the US government in the late 19th century westward to a reservation in what would later become the central state of Oklahoma.

As the new proprietors of the land, the nation in 1906 negotiated a rare agreement with the federal government giving Osage members exclusive mineral rights which could not be transferred or sold, only inherited.

Not long after, prospectors discovered that the Osage Reservation lied on an enormous oil reserve.

With demand for oil skyrocketing, the Osage quickly gained wealth.

In 1923 alone, according to Grann, the nation earned the equivalent of more than $400 million in today's money.

White settlers flocked to the area to take advantage of the black gold windfall.

They set up businesses, married members of the tribe or became managers of the Osage members' fortunes.

In 1921, Congress passed a racist law requiring Native Americans to have a guardian of the oil wealth appointed until they proved their "competency."

- What was the Reign of Terror? -

From 1921 to 1925, a series of murders and suspicious deaths struck the Osage Nation, who have dubbed the period the "Reign of Terror."

Mollie Kyle Burkhart's family was particularly hard-hit. Her sister Anna Kyle Brown was shot in the head in 1921, and their mother Lizzie died a few months later of suspected poisoning.

Rita Smith, another of Mollie's sisters, and husband Bill died after a bomb exploded in their home in 1923.

Their distant cousin, Henry Roan, was also found shot in the head the same year.

The Osage nation states on its website that at least 60 people were killed during this period, but that there were potentially even more murders, as some suspicious deaths were never investigated.

- Federal investigation -

With the death toll mounting, US authorities relaunched an investigation in 1925 under the auspices of the Bureau of Investigation, a forerunner of today's FBI.

After months of investigation, the federal officials uncovered an intra-family plot.

Burkhart's husband Ernest, a white settler, and his uncle William Hale, a wealthy white rancher, had orchestrated the murders in order to take control of their oil rights.

Ernest Burkhart and Hale, after attempting to cover up the crimes, were convicted of murder and received life sentences in 1926 and 1929.

Grann alleges in his book that other murders, which went without convictions due to a lack of evidence, are almost all attributed to people from outside the nation seeking to seize Osage oil rights.

- Today -

Around a quarter of the shares of the reservation's oil rights are held today by non-Osages. Most of the oil has since dried up, however, and royalty checks now amount to only a few thousand dollars.

The Osage Nation is nonetheless pushing for federal legislation that would allow the non-Osages' shares to be gifted or sold back to the nation.

The murders of the 1920s left an indelible mark on the memory of the Osage community, which was heavily involved in the making of Scorsese's film.

Alongside stars Leonardo DiCaprio and Robert De Niro, the film features Osage actors, props made by Osage craftworkers and involved work with Osage language experts.
