A pirate based on the North African Barbary Coast. From the 16th century onward the corsairs plundered shipping in the Mediterranean and Atlantic, holding hostages for ransom or selling them as slaves. Although many punitive expeditions were sent against them, they were not suppressed until France occupied Algiers 1830. Most pirates were Turkish or North African, but there were also many Europeans, such as the Englishman Sir Francis Verney, half-brother of Edmund Verney.
