Works & Achievements
Transformation of Algiers into a corsair state placed under Ottoman protection, a lasting stronghold of Turkish power in North Africa.
Conquest of the Spanish fortress that controlled the harbour of Algiers, freeing the city once and for all from the Spanish coastal threat.
As Kapudan Pasha, he modernized and led the imperial arsenal and navy, making the Ottomans the foremost naval power in the Mediterranean.
Naval battle that secured Ottoman control of the eastern Mediterranean for a generation.
Joint operations with the France of Francis I against Charles V, illustrating the unprecedented diplomatic alliance between a Christian power and the Ottoman Empire.
An account of his conquests dictated to Seyyid Murâd, a major source on Barbary privateering and Ottoman naval expansion.
Anecdotes
Khayr ad-Dîn and his elder brother Arudj (Oruç) began their careers as corsairs in the Mediterranean. Arudj, who had lost an arm in battle, had a silver prosthesis made for himself, which earned him a terrifying reputation before his death in combat near Tlemcen in 1518.
In 1519, unable to hold Algiers alone against the Spanish, Khayr ad-Dîn made a decisive choice: he offered the city to the Ottoman sultan Selim I and received in exchange the title of governor and reinforcements of janissaries. Algiers thus became an Ottoman regency.
In 1533, Suleiman the Magnificent summoned him to Istanbul and appointed him Kapudan Pasha, that is, grand admiral of the entire Ottoman fleet. The corsair of Algiers became the supreme commander of the navy of the most powerful empire of the age.
In 1538, at the Battle of Preveza, Barbarossa crushed an immense Christian fleet commanded by the Genoese admiral Andrea Doria. This victory secured Ottoman dominance over the eastern Mediterranean for nearly thirty years.
In 1543-1544, allied with Francis I against Charles V, Barbarossa wintered with his fleet at Toulon. For his sailors, the city's cathedral was for a time turned into a mosque, and a slave market was held there, to the great embarrassment of Christendom.
Primary Sources

Port on the Greek coast off which Barbarossa won his famous naval victory over Andrea Doria's Christian fleet in 1538.

Daily Life
Morning
In Algiers or aboard his galley, the day of a corsair admiral began early: dawn prayer, inspection of the ships, and listening to the captains' reports. Expeditions were prepared, and supplies and men were counted.
Afternoon
The afternoon was spent governing the regency: dispensing justice, negotiating the ransom of captives, receiving envoys, or organizing raids. At sea, it was the time for maneuvers and watching the enemy coasts.
Evening
In the evening, the officers gathered around their commander to share meals and discuss strategy. At the court of Istanbul, having become Kapudan Pasha, he took part in the sultan's councils and receptions.
Food
Food aboard ship relied on sea biscuit, rice, dried legumes, olive oil, fish, and dried fruit. On land, Ottoman and North African cuisine offered meats, bread, dates, and non-alcoholic drinks in accordance with Islam.
Clothing
As a corsair, he wore loose clothing suited to the sea; as an Ottoman dignitary, he donned a turban, an embroidered caftan, and a belt bearing the saber, the insignia of his rank as admiral.
Housing
In Algiers, he lived in a fortified palace overlooking the harbor; in Istanbul, he had a residence befitting a high dignitary. His true home, however, remained the flagship galley, from which he commanded his fleet.
