Osage Nation
Wahzhazhe
The Osage Nation is a sovereign Tribal Nation headquartered in Pawhuska, Oklahoma. Its history spans homelands in the central Mississippi and Missouri river worlds, nineteenth-century displacement to present-day Oklahoma, and a contemporary constitutional government established by Osage voters in 2006.
Homelands, government, and contemporary presence
Historical homelands
Osage history is connected to a broad central North American homeland, including the Missouri, Arkansas, and central Plains regions. The Nation purchased a reservation in present-day northeastern Oklahoma in the nineteenth century.
Government
A tripartite constitutional government with separate executive, legislative, and judicial branches. The Osage Minerals Council has distinct responsibilities concerning the mineral estate.
Contemporary presence
The Nation governs from Pawhuska and supports language revitalization, education, health, cultural programs, environmental stewardship, economic development, and management of Osage resources.
Executive, legislative, and judicial powers are separated under the 2006 Constitution.
The atlas point marks the government center, not the boundaries of the Osage Reservation or mineral estate.
The Nation identifies a flourishing language as a core public goal.
