Muscogee traditional religion has no single headquarters and no one governing body. It is held by individual ceremonial grounds, called tvlwv, each an independently organized community with its own fire, its own leadership and its own calendar of gatherings, scattered across what is now Oklahoma after nineteenth century removal from the southeastern homeland and, in smaller pockets, surviving in Alabama and Florida among Muscogee people who avoided removal altogether.
Membership in the Muscogee (Creek) Nation, whose 2010 census based self-identification runs to 88,332 people alone or in combination with another race, does not by itself say anything about which of these grounds, if any, a person is connected to, or whether they practice Protestant Christianity, the traditional way, or both together, which is common. What the ceremonial grounds hold in common is the annual cycle built around the Green Corn Ceremony, called Poskita, a renewal built on fasting, the extinguishing and rekindling of the sacred fire, and the stomp dance that carries the ceremony through the night, along with a strict etiquette of who may approach the fire and when.
The Four Mothers Society, formed jointly by Muscogee, Cherokee, Yuchi and other citizens at the turn of the twentieth century specifically to resist allotment, is the clearest institutional trace of how seriously the grounds took the threat of losing communal land: without a shared ceremonial ground, a fire has nowhere to be tended, which is why the grounds, not a church roll, remain the tradition's real unit of continuity today.
