The Osage Reservation

The Osage Reservation in north-central Oklahoma — held by the Nation since 1872 — is the historical anchor for the diaspora’s standing observances and the centre of gravity for the sister entities’ coordination work.

The traditional territory of the Wah-Zha-Zhe

The Wah-Zha-Zhe carry an inheritance of land far larger than the present reservation. Before the cessions of the nineteenth century, Osage territory comprised, at its greatest extent, much of present-day Missouri and Arkansas, the eastern half of Kansas, the northern reaches of Oklahoma and Texas, and parts of Iowa and Nebraska — a continuous domain of more than fifty million acres between the Missouri, the Arkansas, and the Red rivers, with the Ozarks at the eastern edge and the Wichitas to the south.

The cessions and treaties through which that territory was taken are matters of public record. Osage Group operates with a standing acknowledgement of that history; it does not presume to redress it. Where the Group’s capital flows into land or mineral interests within the historical territory, those interests are operated under Osage Capital and Osage Farm under the same in-common discipline that governs the headright system.

• 1808 — Treaty of Fort Clark; first major cession.
• 1818, 1825, 1839 — Successive cessions through the Treaty of St. Louis and Osage Treaty.
• 1865–1866 — Fort Smith Council and treaty; the Diminished Reserve.
• 1872 — The Osage purchase the present 1.47 million-acre reservation in Indian Territory.
• 1907 — Allotment Act. Surface allotted; the mineral estate kept in common.
• 1925, 1978, 2004 — Successive federal Acts confirming and modernising tribal mineral and citizenship rights.
• 2006 — Present Osage Nation Constitution ratified; one citizen, one vote.

The diaspora

The 2023 tribal census recorded Osage citizens in all fifty U.S. states and at least eleven countries. Osage Group maintains standing relationships across the diaspora, in particular through:

• The Cyrus / PARS Foundation (Persian diaspora) under the standing partnership of 2026.
• Long-running cooperation with Indigenous-led civil-society organisations across North America, the Pacific, and Africa, through Osage NGO.
• Academic and museum partnerships through the Osage Institute and the Wazhazhe Archive.

Sovereignty boundary

The Osage Nation, a federally recognised sovereign tribal government, is the rightful authority over the present reservation and over the Nation’s relations with foreign powers. Osage Group’s footprint is the diaspora’s working footprint; it is not the Nation’s. The Nation speaks for itself at osagenation-nsn.gov.
