The
Tampa Bay area was visited by Spanish explorers during
Florida's early Spanish period. In 1528, an
expedition led by
Pánfilo de Narváez landed near
Tampa Bay and soon skirmished with the indigenous population, probably at the principal town of the Tocobaga at the
Safety Harbor site. Several years later, the
Hernando de Soto Expedition likely landed on the southern shore of Tampa Bay in 1539, and passed through the eastern part of Safety Harbor territory after occupying the village of
Uzita.
Garcilaso de la Vega (known as
el Inca), in his history of de Soto's expedition, relates that Narváez had ordered that the nose of the chief of Uzita be cut off, indicating that the two explorers had passed through the same area. Another town near Uzita encountered by de Soto was
Mocoso, but evidence suggests that, while Mocoso was in the Safety Harbor culture area together with Uzita and Tocobaga, the Mocoso people spoke a different language, possibly
Timucua. Neither Narvaez nor de Soto remained in the area for long, as they each traveled north in search of gold after several violent encounters with the Tocobaga and their neighbors. The
missionary expedition of Father
Luis de Cancer visited the Tampa Bay area in 1549 to attempt to peacefully convert the locals to Christianity. He intended to build a relationship between the Spanish and indigenous Floridians in the aftermath of earlier visits by aggressive conquistadors. Despite being cautioned to avoid the Gulf Coast, Father Cancer's expedition came ashore just south of the mouth of
Bahia Espiritu Santo (Tampa Bay) in May 1549. There they encountered apparently peaceful and receptive Natives who told them of the many populous villages around Tampa Bay. Father Cancer decided to continue north to visit these towns and was met with violent resistance. Most members of the expedition were killed or captured, and Father Cancer was clubbed to death soon after reaching modern day Pinellas County.
Hernando de Escalante Fontaneda, a shipwreck survivor who lived with the Natives of southern Florida from 1549–1566 and was rescued from the
Calusa by
Pedro Menéndez de Avilés, described Tocobaga, Abalachi (
Apalachee) and Mogoso (Mocoço) as "separate kingdoms" from the Calusa. Ucita and Mocoço at the time of de Soto's visit were subject to a chief named
Urriparacoxi or Paracoxi (also given as Urribarracuxi). De Soto marched to the town of Paracoxi, which appears to have been inland from Tampa Bay, where he found
maize being cultivated. (By contrast, the Safety Harbor people made little or no use of maize, and instead gathered most of their food and resources from the bountiful coastal waters.) The name "Tocobaga" first appears in Spanish documents in 1567, when
Pedro Menéndez de Avilés visited what was almost certainly the Safety Harbor site. Menéndez had contacted the
Calusa and reached an accommodation with
Carlos, the Calusa king. Menéndez married Carlos's sister. As Carlos was anxious to gain an advantage over his enemy Tocobaga, Menéndez took Carlos and 20 of his warriors to Tocobaga by ship. Menéndez persuaded Tocobaga and Carlos to make peace. He recovered several Europeans and a dozen Calusa being held as slaves by Tocobaga. Leaving a garrison of 30 men at Tocobaga ( to encourage the people of the town to convert to Christianity), he returned Carlos and the other Calusa to their town. In January 1568, Spanish boats taking supplies to the garrison at Tocobaga found the town deserted, and all the Spanish soldiers dead. ==Later history==
