Pinellas County (, ) is a county located on the west central coast of the U.S. state of Florida. As of the 2020 census, the population was 959,107. It is the most densely populated county in Florida. The county is part of the Tampa–St. Petersburg–Clearwater, Florida Metropolitan Statistical Area. Clearwater is the county seat. St. Petersburg is the largest city as well as the largest city in Florida that is not a county seat. History Pre-European settlement When Europeans first reached the Pinellas peninsula, the Tampa Bay area was inhabited by people of the Safety Harbor culture. The Safety Harbor culture area was divided into chiefdoms. One documented chiefdom in what is now Pinellas County was that of the Tocobaga, who occupied a town and large temple mound, the Safety Harbor site, overlooking the bay in what is now Safety Harbor. The modern site is protected and can be visited as part of the County's Philippe Park. Spanish and British Florida During the early 16th century Spanish explorers discovered and slowly began exploring Florida, including Tampa Bay. In 1528 Panfilo de Narvaez landed in Pinellas, and 10 years later Hernando de Soto is thought to have explored the Tampa Bay Area. By the early 18th century the Tocobaga had been virtually annihilated, having fallen victim to European diseases from which they had no immunity, as well as European conflicts. Later Spanish explorers named the area Punta Piñal (Spanish for "Point of Pines" or "Piney Point"). After trading hands multiple times between the British and the Spanish, Spain finally ceded Florida to the United States in 1821, and in 1823 the U.S. Army established Fort Brooke (later Tampa). Settlement of West Hillsborough In 1834 much of west central Florida, including the Pinellas peninsula (then known simply as West Hillsborough), was organized as Hillsborough County. The very next year Odet Philippe, a French Huguenot from Charleston, South Carolina became the first permanent, non-native resident of the peninsula when he established a plantation near the site of the Tocobaga village in Safety Harbor. It was Philippe who first introduced both citrus culture and cigar-making to Florida. Around the same time, the United States Army began construction of Fort Harrison, named after William Henry Harrison, as a rest post for soldiers from nearby Fort Brooke during the Second Seminole War. The new fort was located on a bluff overlooking Clear Water Harbor, which later
