The Calusa were a powerful Native American civilization who dominated Southwest Florida for centuries before European contact. Known as the “Shell People,” they engineered complex canal systems, shell mounds, and ceremonial centers without practicing agriculture, relying instead on fishing and maritime trade. Their capital near present-day Mound Key reflected sophisticated political leadership and social structure. This presentation explores Calusa innovation, spiritual beliefs, environmental mastery, and their encounters with Spanish explorers—revealing a resilient and influential culture that shaped Florida’s early history.
