Across history n' the world o'er there have been many who be dubbed "Pirates!" Sometimes ye will have regional varieties that be immediately identifiable by an age old nickname, such as the Barbary Corsairs. Fer Caribbean Pirates ye would likely hear the term Buccaneer. It's certainly popular enough that arrr own Tampa Bucs use it fer their sports team!
Buccaneers have incredibly humble origins, they did not start out as cut throats n' rogues. In the early 17th Century Hispaniola was home to many French hunters who had no land of thar own, who made their living huntin' n' barbecuing wild boar n' other creatures. Thar Smoke Huts were referred to as boucanes, where they cooked all of the meat they harvested from the local wild life usin' Native Caribbean techniques. Effectively they cooked the predecessor to Jerked Meat, as well as Jerky!
Off the coast of these wild islands the "Boucaniers" would see Spanish Treasure ships returning to Europe with New World Riches, as well as the raiders n' early Caribbean pirates that would prey on their cargo. The hunters sold their meats to the pirates n' it didn't take them too long for many o' them to teach the pirates to cook Buccaneer style, n' for the Hunters to learn how to be Pirates!
Usin' thar small sailin' vessels meant to deftly navigate Caribbean islands they learned to creep aboard Spanish merchant ships n' became natural enemies of the Empire. O'ertime the Anglicized word Buccaneer became synonymous with Pirate or Privateer regardless o' nation.
Fer much o' the 17th Century Hispaniola became a large point o' contention between these Buccaneers n' the Spanish. One o' the most popular pirate havens, Tortuga was on a small isle off the northwest coast of Haiti, it was a popular hangout for French Buccaneers!
