2026 Osage Nation Sovereignty Celebration

Each March, the Osage Nation Sovereignty Celebration honors a defining moment in our history—the ratification of the Osage Nation Constitution on March 11, 2006. This year is especially meaningful as we commemorate the 20th anniversary of our Constitution, a milestone that reflects our strength, resilience, and self-determination. Throughout the month, our people and community will come together to celebrate Osage sovereignty and look ahead to the future we continue to build together. 

This webpage will serve as the central hub for all Sovereignty Celebration events, announcements, and updates. More events and details coming soon - stay tuned! Questions? Email communications@osagenation-nsn.gov
