Answer
Jean Barbarossa controlled the fleets of corsairs in Salé-le-Vieux and Salé-le-Neuf. Salé-le-Vieux was a port city on the Atlantic coast of Morocco, and Salé-le-Neuf was a nearby city that was founded by Barbarossa and his brothers. The two cities were the main bases for the Barbarossa brothers' fleets of corsairs, and they were used to launch raids on Christian shipping in the Mediterranean Sea.
