The earliest known inhabitants were prehistoric Indians who entered what is now northern Florida some 10,000 to 20,000 years ago. These people were almost exclusively big-game hunters who followed wandering animal herds. Around 5000 B.C ., permanent settlements were being established as some Indians turned to fishing. Agriculture was begun about 1400 B.C . Nearly 1,500 years later, the Indian occupation had been extended across the entire peninsula. Historians estimate that on the eve of the European discovery of Florida in the 16th century A.D. the Indian population totaled about 25,000. The major groups were the Timucua, Calusa, Ais, Apalachee, and Tequesta. The Seminoles arrived about two centuries later.
