I got this information also from the Chieftains Trail from Calhoun, Georgia.
Prior to the early 18th Century, most of Georgia and Alabama was home to Native Americans belonging to a southeastern alliance known as the Creek Confederacy. Today's Creak Nation, also know as the Muskogee, was the major tribe alliance.
According to Creek traditions, the Confederacy migrated to the southeastern United States from the Southwest. The confederacy was probably formed as a defense against other large groups to the north.
The name "Creek" came from the shortening of "Ocheese Creek" Indians - a name given by English to the native people living along the Ocheese Creek (Ocmulgee River). In time, the name was applied to all groups of the confederacy.
Most of the groups of the confederacy shared the same language (Muskogen), types of ceremonies, and village lay-out.
The Creek people lived in large permanent towns which were centered around plazas used for dancing, religious ceremonies and games. The Plazas also contained a rotunda - a round building made of poles and mud and used for council meetings - and an open-air summer council house. Surrounding the plaza area were the family homes.
Towns were governed by a Chief, or "Mico," an Assistant Chief, and a "Mico Apokta," who acted as speaker for the Chief, announcing his decisions to the people.
These characteristics are very similar to what is know about the prehistoric Mississippian Culture who occupied the Etowah Mounds village. Thus, the Etowahian people are believed to be the ancestors of the Creeks who lived in the area until the early 1700's.
The modern capitol of the Creek Nation is in Okumlgee, OK.
