 Oral traditions passed down by the ancestors of the Creeks have alleged that their nation migrated eastward from places West of the Mississippi River, eventually settling on the east bank of the Ocmulgee River.It was here that they waged war with other bands of Native American Indians, as the Savannas, Ogeeches, Wapoos, Santees, Yamafees, Utinas, Icofans, Paticans and others, until at length they had extirpated them.At the time the Spanish made their first forays inland from the shores of the Gulf of Mexico, many political centers of the Mississippians were already in decline, or abandoned.
