After the disappearance of the indigenous populations, there were no permanent settlements in the Tampa Bay area until after the United States acquired Florida from Spain in 1821.
The Civil War ended in April 1865 with a Confederate defeat.
While there is a substantial historical record of the Tocobaga (and the Calusa, who lived far to the south), there is less surviving documentation describing the Pohoy chiefdom, which controlled the area near the mouth of the Hillsborough River near today's downtown Tampa.
However, brief mentions by explorers along with surviving artifacts suggest that the Pohoy and other groups that once lived on Tampa Bay had very similar cultures and lifestyles as the better-documented Tocobaga.
The first iteration of the name "Tampa" first appears in the memoirs of Hernando de Escalante Fontaneda (1575), who had spent 17 years as a Calusa captive and traveled through much of peninsular Florida.
He spelled it "Tanpa" and describes it as an important Calusa town on the west coast.
