Symbolism & heraldry
The shield is a traditional Osage warrior's shield. The eagle feathers represent honour; the calumet (Native American peace pipe) and olive branch (European peace symbol) crossed beneath show the meeting of cultures. The blue field is taken from the Choctaw Nation's historic flag.
Heraldic elements on the Flag of Oklahoma — bands, charges, emblems or stars — each carry meaning agreed at the moment of the flag’s adoption. Re-readings happen across generations: a colour or a symbol that began with one meaning often picks up further layers as the country’s history unfolds.
Adoption & history
The current flag was adopted in 1925. It is credited to Louise Funk Fluke. Earlier banners flown by Flag of Oklahoma reflected the politics of their day; each redesign typically marked a moment of independence, regime change or constitutional reform. The current flag was chosen, debated and codified through the country’s official channels and is now protected by flag law.
Etiquette & protocol
The Flag of Oklahoma should be flown with respect: never allowed to touch the ground, never used as drapery for ceremonies it was not made for, and lowered or removed at sundown unless illuminated. When flown alongside other national flags, it takes precedence on home soil and is hoisted first and lowered last. On days of national mourning, the flag is flown at half-mast in line with directives from the head of state. These conventions are common to most nations and are usually written into the flag’s founding statute.
