The Kapudan Pasha (Ottoman Turkish: قپودان پاشا, modern Turkish: Kaptan Paşa), was the Grand Admiral of the navy of the Ottoman Empire. He was also known as the Kapudan-ı Derya (Ottoman: قپودان دریا, modern: Kaptan-ı Derya, "Captain of the Sea"). Typically, he was based at Galata and Gallipoli during the winter and charged with annual sailings during the summer months. The title of Kapudan Pasha itself is only attested from 1567 onwards; earlier designations for the supreme commander of the fleet include Derya Bey ("bey of the sea") and Re'is Kapudan ("head captain").
The title Derya Bey was first granted during the reign of Bayezid I as an official rank within the state structure. Following the Conquest of Constantinople, Mehmet II raised Baltaoğlu Süleyman Bey to the status of sanjak bey for his efforts against the Byzantines in the Golden Horn. Baltaoğlu received the sanjak of Gallipoli (the principal Turkish naval base) and the kazas of Galata (until the Conquest a Genovese colony) and İzmit (whose tax remittance consisted of ship timber).
The success of Hayreddin Barbarossa saw the Kapudan Pasha elevated to the ranks of beylerbey and vizier in 1535, with his territories expanded into the Eyalet of the Archipelago and Algiers. Hayreddin's successors succeeded to these holdings, but saw their rank drop to two-horsetail vizier for several centuries.
The official residence of the Kapudan Pasha was in the Divankhane in the Imperial Arsenal in the Golden Horn, but he was often away as his governorship of the Eyalet of the Archipelago entailed visiting its various provinces in person every year. The post was one of great power and prestige within the Ottoman hierarchy: Evliya Çelebi reports that it had an annual income of 885,000 silver akçes. Additional income, to the amount of 300,000 kuruş in the 18th/19th centuries, came from leasing a number of Aegean islands to tax farmers (iltizam).
The heyday of the post was in the 16th century, when a succession of capable holders brought Ottoman naval power to its height, and for a time ensured its supremacy in the Mediterranean. Although in theory the post could only be filled by a serving admiral (Kapudan-i Hümayn), a chief of the Imperial Arsenal (Tersane Kethüdasi) or, at the very least, by the sanjak-bey of Rhodes, from the turn of the 17th century the appointment of court favourites and/or persons lacking in military or naval experience marked the beginning of Ottoman naval decline.
As a part of the Tanzimat reforms, the Eyalet of the Archipelago was reduced in rank and granted to the wali of Rhodes in 1848. The Kapudan Pashas retained their rank but were thereafter solely military servicemen.
A total of 161 captains served until 13 March 1867 when the post was abolished and replaced by ministers (Bahriye Nazırı) of the Ottoman Naval Ministry. After 1877, these were replaced by the Fleet Commanders.
