Letters of marque in the context of "Port Royal"

Port Royal (Jamaican Patois: Puot Rayal) was a town located at the end of the Palisadoes, at the mouth of Kingston Harbour, in southeastern Jamaica. Founded in 1494 by the Spanish, it was once the largest and most prosperous city in the Caribbean, functioning as the centre of shipping and commerce in the Caribbean Sea by the latter half of the 17th century. It was destroyed by an earthquake on 7 June 1692 and its accompanying tsunami, leading to the establishment of Kingston, the capital and the most populated and prosperous city in Jamaica. Severe hurricanes have regularly damaged the area. Another severe earthquake occurred in 1907.

Port Royal became home port to English and Dutch government sponsored privateers who were encouraged to attack Spanish vessels, at a time when many European nations were reluctant to attack the powerful Spanish fleet directly. As a port city, it was notorious for its gaudy displays of wealth and loose morals, with the privateer crews spending their treasure in the many taverns, gambling houses and brothels which catered for the sailors. When the British and Dutch governments officially abandoned the practice of issuing letters of marque to privateers against the Spanish treasure fleets and possessions in South America in the later 16th century, many of the crews turned pirate to allow themselves to maintain their plundering illegally. Port Royal effectively became a pirate republic, and they continued to use the city as their main base during the 17th century. Pirates from around the world congregated at Port Royal, coming from waters as far away as Madagascar. The town became notorious in folklore as "the wickedest city on Earth".
