Arudj Barberousse
Born on Lesbos, Khizr began his naval career as a corsair under his elder brother Oruç Reis. In 1516, the brothers captured Algiers from Spain, with Oruç declaring himself as Sultan. Following Oruç's death in 1518, Khizr inherited his brother's nickname, "Barbarossa" ("Redbeard" in Italian). He also received the honorary name "Hayreddin" (from Arabic "Khayr ad-Din", "goodness of the faith" or "best of the faith"). In 1529, Barbarossa retook the Peñón of Algiers from the Spaniards.
