About Us

Why Calusa Security

We believe that the history of the native Americans who lived in Southwest Florida is very important to preserve and honor that’s why we named the company after them.  The Taíno were an Arawak people who were the indigenous people of the Caribbean and Florida. At the time of European contact, in the late 15th century, they were the principal inhabitants of most of Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), and Puerto Rico.

In the Greater Antilles, the northern Lesser Antilles, and the Bahamas, they were known as the Lucayans and spoke the Taíno language, a derivative of the Arawakan languages.

The ancestors of the Taíno entered the Caribbean from South America. At the time of contact, the Taíno were divided into three broad groups, known as the Western Taíno (Jamaica, most of Cuba, and the Bahamas), the Classic Taíno (Hispaniola and Puerto Rico) and the Eastern Taíno (northern Lesser Antilles). A fourth, lesser-known group went on to travel to Florida and divided into tribes. At present, we know there are four named tribes: the Tequesta, Calusa, Jaega and Ais. Other tribes are known to have settled in Florida, but their names are not known.

The Calusa was a powerful, complex society who lived on the shores of the southwest Florida coast. Their main waterway was the Calooshahatchee River, which means River of the Calusa.  They had a reputation from being a fierce, war-like people, especially among European explorers and smaller tribes.

Known as the “Shell Indians”, the Calusa are considered to be the first shell collectors. Unlike other tribes, the Calusa did not  make any items from pottery. Shells were used to make items like jewelry, utensils and tools. They discarded shells into huge piles, called mounds, which can still be found in many parts of Florida today. Many groups protect the remaining shell mounds, while archaeologists have studied them to learn about this tribe.

With a population estimated to be around 50,000, they controlled most of Florida. Because they lived along the coast, they were excellent sailors. They defended their lands against other small tribes and European explorers. The Calusa travelled by dugout canoes which were made from hollowed-out cypress logs. These logs were about 15 feet long. The Calusa used the canoes to travel as far as Cuba, and to sail up and down the coast salvaging goods from shipwrecks.

By the late 1700s, the Calusa had died out. Diseases such as smallpox and measles were brought into their territory from European explorers, which wiped out entire villages. Many Calusa were captured and sold as slaves. Some believe the remaining members of the Calusa tribe left for Cuba once the Spanish gave Florida to the British in 1763. Once the Calusa disappeared enemy tribes began raiding their territory.
