The Seminole Indians were relatively late arrivals to the Florida peninsula; the Apalachees, Calusas, Timucuans, and smaller tribes had settled the area much earlier. The Seminole migrations into Florida came in three distinct phases: in the period between 1702-1750, they made raids against the Spainards and their Indian allies, and although the Seminoles acquired much knowledge of the Florida terrain, no significant settlements were made. In the period 1750-1812, six or more villages were established in the northern part of Florida, and small parties explored the entire peninsula in search of deer, bear, and other game, and to make contact with Cuban fishermen. The third phase came between the years of 1812-1820, when pressures in Alabama and Georgia forced the Upper and Lower Creeks to move south into Florida.
