operated from North Africa, based primarily in the ports of Algiers, Tunis and Tripoli. This area was known in Europe as the Barbary Coast, a term derived from the name of its Berber inhabitants. Their predation extended throughout the Mediterranean, south along West Africa's Atlantic seaboard and even South America, and into the North Atlantic as far north as Iceland, but they primarily operated in the western Mediterranean. In addition to seizing ships, they engaged in Razzias, raids on European coastal towns and villages, mainly in Italy, France, Spain, and Portugal, but also in the British Isles, the Netherlands and as far away as Iceland. The main purpose of their attacks was to capture Christian slaves for the Muslim market in North Africa and the Middle East.
