The Timucua were a Native American people who lived in Northeast and North Central Florida and southeast Georgia. They were the largest indigenous group in that area and consisted of about 35 chiefdoms, many leading thousands of people. The various groups of Timucua spoke several dialects of the Timucua language. At the time of European contact, Timucuan speakers occupied about 19,200 square miles (50,000 km2) in the present-day states of Florida and Georgia, with an estimated population of 200,000. Milanich notes that the population density calculated from those figures, 10.4 per square mile (4.0/km2) is close to the population densities calculated by other authors for the Bahamas and for Hispaniola at the time of first European contact. The territory occupied by Timucua speakers stretched from the Altamaha River and Cumberland Island in present-day Georgia as far south as Lake George in central Florida, and from the Atlantic Ocean west to the Aucilla River in the Florida Panhandle, though it reached the Gulf of Mexico at no more than a couple of points.

Florida is a state in the Southeastern region of the United States. It borders the Gulf of Mexico to the west, Alabama to the northwest, Georgia to the north, the Atlantic Ocean to the east; and the Straits of Florida and Cuba to the south. About two-thirds of Florida occupies a peninsula between the Gulf of Mexico and the Atlantic Ocean. It has the longest coastline in the contiguous United States, spanning approximately 1,350 miles (2,170 km), not including its many barrier islands. It is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. With a population of over 21 million, it is the third-most populous state in the United States and ranks eighth in population density as of 2020. Florida spans 65,758 square miles (170,310 km2), ranking 22nd in area among the states. The Miami metropolitan area, anchored by the cities of Miami, Fort Lauderdale, and West Palm Beach, is the state's largest metropolitan area, with a population of 6.138 million; the most populous city is Jacksonville. Florida's other major population centers include Tampa Bay, Orlando, Cape Coral, and the state capital of Tallahassee.
