More than a century ago, the Osage Nation, whose government had just been dismantled by the US, negotiated a unique arrangement: All the mineral rights to its nearly 1.5 million-acre reservation would be put in a federally managed trust. Those rights soared in value when oil drilling took off in the state in the 1910s, and tales of Osage wealth swept the country — many exaggerated and racist, painting rich Osages as unworthy and financially reckless. The Osage people were supposed to be safeguarded by the US government because of the agreement their leaders negotiated. Instead, federal policies allowed a massive transfer of Osage land and wealth to outsiders that the Osage Nation is now working to get back.
