Historically, the Barbary Coast contained a number of pirate havens, notably Salé, Algiers and Tunis. These pirate havens were used by Corsairs from the 16th to the 19th century. The pirates, dubbed "Barbary Pirates", ravaged European shipping and enslaved thousands of captives. The Pirate Republic of Salé, in 17th century Morocco, was a micronation with its own seaport argot known as "Franco," since like other pirate states, it from time to time made treaties with European governments, agreeing not to attack their fleets.
