South-central Florida’s aboriginal inhabitants remain among the least known of Florida’s native peoples during the first Spanish period because Spaniards did not maintain a permanent presence among them. It is likely that a number of the region’s tribes disappeared without even their names having been recorded. That is true particularly of the peoples living in the interior beyond the southernmost missions and those living on or near the Gulf coast between Tampa Bay’s southern shore and the Caloosahatchee River. Some of those peoples began to appear fleetingly in Spanish records during the 1710-1740 period when attacks by Indians allied to the British of South Carolina and Georgia forced them to seek refuge intermittently in the vicinity of St. Augustine.
