Turkey commemorated Thursday the 473rd anniversary of the passing of the first admiral of the Ottoman navy, Barbaros Hayrettin Pasa. Centuries after his demise, he is still considered to be one of the best sailors in the history. Commander of Naval Forces Barbaros Hayrettin Pasa was born on the island of Lesbos, Greece in 1478. Known as Barbaros Hayrettin, Oruc was the real name of the Ottoman admiral. It was his brother Oruc Reis whom Westerners nicknamed 'Barbarossa' for his red beard. After Oruc's death, Hizir was called with the same nickname. He was given the name 'Hayrettin' by Ottoman Sultan Selim I, also known as Yavuz Sultan Selim. The youngest of the four brothers, Hizir began trading activities between Lesbos, Thessaloniki and Euboea of Greece with a ship he had built. After the rescuing his brother Oruc from Knights of Rhodes, the two brothers declared loyalty to Ottoman Prince Sehzade Korkut, brother of Selim I. After 1504, Hizir and Oruc engaged in a struggle for dominance against Spain, Genoa and France in the Mediterranean, and declared victory. Taking the reign of Algeria in 1516, Hizir later offered his land to the Ottomans with a delegation sent to Selim I. Algeria became an Ottoman territory with this move.
