South of Tampa Bay lay a kingdom. The Calusa, the dominant people of southwest Florida, built one of the most powerful and complex societies in precontact North America, and they did it, like the Tocobaga to their north, almost entirely on the harvest of the sea. They held the shipwrecked boy Fontaneda captive for seventeen years, they fought the Spanish to a standstill for two centuries, and it was in their country, not on Mullet Key, that Ponce de Leon received his death wound.
The Calusa controlled the coast and waters of southwest Florida, centered on Charlotte Harbor, the Caloosahatchee River, and Estero Bay, with their capital town of Calos on Mound Key. Like the Tocobaga, they were not farmers; the estuaries were so rich that they could support a dense population, a powerful paramount chief, social hierarchy, and monumental construction on fishing alone. They raised enormous mounds and middens of shell, engineered canals and water courts, and commanded a network of subordinate towns that paid them tribute. The Spanish, who knew real kingdoms when they saw them, treated the Calusa ruler as a king.
The Calusa met the Spanish with force. When Juan Ponce de Leon returned to Florida in 1521 to plant a colony, he came ashore in southwest Florida, in Calusa country, and the Calusa attacked. Ponce was struck by an arrow, and the wound killed him; he was carried to Cuba, where he died. This is the crucial geographic fact behind a stubborn local legend. Popular Tampa Bay histories have sometimes claimed that Ponce was mortally wounded at Mullet Key. He was not. The best evidence places his death wound firmly in Calusa territory to the south, around Charlotte Harbor or the Caloosahatchee, and this archive records the Mullet Key version as folklore, not fact. The Calusa, not the Tocobaga, are the people who ended Ponce de Leon.
The Calusa are also the people who held Hernando de Escalante Fontaneda, the Spanish boy shipwrecked on the Florida coast in 1549, for some seventeen years. They sacrificed most of the survivors of his wreck, including his brother; Fontaneda lived, by his own account, because he correctly understood and obeyed their commands to sing and dance. It is from his later memoir, written from the inside of Calusa society, that much of what we know about them comes, including the tangled history of the name Tampa, which he recorded as a town in the south, likely in or near Calusa country, before the name migrated north to the bay we now call Tampa.
The Calusa king of Fontaneda's era was the man the Spanish called Carlos, who ruled from the capital town of Calos on Mound Key. When Pedro Menendez de Aviles came seeking alliance in 1566, he sealed a fragile peace with Carlos by marrying the king's sister, who was baptized Dona Antonia and carried back and forth as a hostage of the bargain. It was Menendez who ransomed Fontaneda out of his long captivity. But the peace did not hold: Menendez's parallel dealing with the Calusa's enemies, the Tocobaga of Tampa Bay, helped sour the alliance, and within a few years the Spanish had killed Carlos's successor and abandoned their mission among the Calusa. The kingdom had repelled Spain again.
The Calusa resisted Spanish missions and Spanish authority more successfully and for longer than almost any people in Florida, repeatedly expelling or killing the priests and soldiers sent among them, in the very years Pedro Menendez was also failing to hold the Tocobaga at Tampa Bay. But what the Spanish could not do by force, disease and the slave trade did by attrition. Through the seventeenth and early eighteenth centuries, European epidemics and slave raids by English-allied groups from the north ground the Calusa down, and by the mid-1700s the survivors had largely fled to the Florida Keys and to Cuba. The great kingdom of the southwest coast was gone, like the Tocobaga, before the United States ever existed.
