The Osage Shield is the center image of the Oklahoma state flag.
The Osage shield is covered by two symbols of peace: the Plains-style ceremonial pipe representing Native Americans, and the olive branch representing European Americans. Six golden brown crosses, Native American symbols for stars, are spaced on the shield. The blue field is inspired by the Choctaw flag adopted by the tribe in 1860.
The blue field also represents devotion. The shield surmounted by the calumet and olive branch represents defensive or protective warfare, showing a love of peace by a united people.
