Calusa

The Calusa (/kəˈluːsə/ kə-LOO-sə) were a Native American people of Florida's southwest coast. Calusa society developed from that of archaic peoples of the Everglades region. Previous indigenous cultures had lived in the area for thousands of years.

At the time of European contact in the 16th and 17th centuries, the historic Calusa were the people of the Caloosahatchee culture. They are notable for having developed a complex culture based on estuarine fisheries rather than agriculture. Calusa territory reached from Charlotte Harbor to Cape Sable, all of present-day Charlotte and Lee counties, and may have included the Florida Keys at times. They had the highest population density of south Florida; estimates of total population at the time of European contact range from 10,000 to several times that, but these are still speculative.
