Barbaros Hairetin Pasha, also known as Heather Hairetin Pasha and simply Heather Reiss (c. 1466/1478 – 4 July 1546), was an Ottoman corsair and later admiral in the Ottoman fleet. Barbarossa’s naval victories secured Ottoman rule over the Mediterranean in the mid-16th century.
Born in Lesvos, Khizr began his naval career as a corsair with his older brother Oruch Reis. In 1516 the brothers conquered Algeria from Spain and Oruch proclaimed himself sultan. After Oruch’s death in 1518, Heather inherited her older sister’s nickname “Barbarossa” (“Red Beard” in Italian). He was also given the honorary title Hayreddin (from the Arabic Khayr ad-Din, “the good of the faith” or “the best of the faith”). In 1529 Barbarossa conquered the Algerian Penon from Spain.
In 1533, Barbarossa was appointed Kapudan Pasha (grand admiral) of the Ottoman fleet by Suleiman the Magnificent. He headed the embassy in France that same year, conquered Tunisia in 1534, won a decisive victory over the Holy League at Preveza in 1538, and campaigned together with France in the 1540s. Barbarossa retired to Constantinople in 1545
