Murat Reis the Elder (Turkish: Koca Murat Reis; c. 1534–1609) was an Albanian privateer and admiral of the Ottoman Navy. He is regarded as one of the most important Barbary corsairs.
Born into an Albanian family in Rhodes or Albania in 1534 he began his career when he joined the crew of Turgut Reis at a very young age. He also fought alongside Piri Reis in several expeditions. In 1534 Murat Reis accompanied Barbarossa Hayreddin Pasha to Constantinople where they were received by Suleiman I and appointed to take command of the Ottoman fleet. While in Constantinople, Murat Reis participated in the construction of new warships at the naval arsenal on the Golden Horn.
Murat Reis took part in all of the early naval campaigns of Turgut Reis. On September 25 and 26, 1538, he was assigned with the task of preventing the ships of the Holy League under the command of Andrea Doria from landing at Preveza, and he successfully repulsed them from the shoreline. On September 28, he took part in the main combat and played an important role in the Ottoman victory at the Battle of Preveza, where he fought along with Turgut Reis in the center-rear wing of the Ottoman fleet which had a Y shaped battle configuration. He continued to accompany Turgut Reis until being assigned as the Commander-in-Chief of the Indian Ocean fleet.
In 1570 Murat Reis, in command of a fleet of 25 galleys, was assigned with the task of clearing the area between Crete, Rhodes and Cyprus for the build-up of the naval siege and eventual conquest of Cyprus. He was also assigned with the task of blocking the Venetian ships based in Crete from sailing to Cyprus and assisting the Venetian forces in that island. He continued to undertake this task until the eventual surrender of Famagusta, the final Venetian stronghold on the island.
