Which native american tribe in florida began attacking settlers both in florida and in georgia in the early 1800s

The written records of Florida begin in 1513, with the Spanish explorer Juan Ponce de Leon. The mass of land that he explored on the American continent would come to be named La Florida, in honour of Pascua Florida (Feast of Flowers), which is the name given to Spain's Easter time celebration. By this time the Spanish had established Spanish hegemony in New Spain and much of the Caribbean. The Spanish soon considered Florida a vital asset in protecting the shipping routes they used to send bullion and other supplies back to Europe, especially since privateering was rampant at this time. With the French in Louisiana, Spanish colonization of Florida held the threat of cutting off their supplies routes to France. To the British, which had interests in the Caribbean and along the east coast, eventual colonization down the coast made conflict all but assured. Thus, Florida would become a focus for British, French, and Spanish colonization. This left many of the native tribes in Florida in a precarious position as they had to deal with the three imperial powers trying to establish dominance, each as likely to prosecute them for any multitude of reasons, but all resulting in exploitation. By the end of the 17th century most of the native tribes would be largely wiped out or nearly exterminated from disease and European aggression.

The Seminole, led by Osceola, led attacks on settlers in Florida and Georgia and then avoided capture by retreating into the Everglades where the territory was so unforgiving as to make pursuit impossible.
