Interpreting the treaty in its strictest sense, Mohammed, after arranging a peace with Venice, occupied the Ionian Islands, and soon afterwards showed his contempt for the military powers of Western Europe by sending a fleet of 150 ships to Otranto in Apulia, a province of the kingdom of Naples. The town, entirely unprepared for such a raid, was taken in 1480; the garrison and the archbishop were put to death, and the neighboring country was organized as a Turkish province with its capital at Otranto, where a garrison of 5000 Turkish soldiers was left behind. The alarm created by this feat of arms was instantaneous. The Italian cities united and soon expelled the Turks from the peninsula, rivaling their enemies in Asiatic deeds of cruelty. Mohammed could not prosecute the conquest of Italy, because his attention was necessarily divided by the troubled state of Turkish rule in Asia, where the Seldjouk principalities still claimed an autonomy which, on crucial matters, made them independent of the Sultan. In the north of Anatolia, which was directly in the hands of the Ottomans, there still remained the Empire of Trebizond, governed by a Greek prince, David Comnenus. Part of his dominions, Sinope and Paphlagonia, were conquered in 1461, and then the last Emperor of Trebizond turned for help to his Turkoman ally, Hassan, ruler of Armenia and part of Persia. Mohammed struck at his foes rapidly. Marching on Erzeroum, he forced Hassan to sue for peace, and so the Greek Emperor was left to meet the Turks unaided. The city of Trebizond was effectively encircled by land and sea, and David was soon brought to surrender, and afterwards, with many members of his household, was put to death. Equally implacable was Mohammed to the Seldjoukian emirates. At the death of Ibrahim, the Prince of Karamania, the Sultan intervened, while seven claimants were disputing over the succession, and after several campaigns annexed the emirate. Hassan’s time soon came. Feeling the insecurity of his rule, he asked help of Rhodes and Venice, especially requesting to be furnished with artillery, by the aid of which so many of the Ottoman victories were won. Two hundred Italian gunners were sent in answer to his call. In 1472 he took the Ottoman town of Tokat, and sacked it. This act caused Mohammed to take up the war against him in person. The two armies met on July 26, 1473, at Outlouk-Bali, near Terdjan, where a decisive victory was won by the Sultan. All the prisoners taken were massacred. The Turkomans had no desire to contest further the predominance of Ottoman rule, which was now extended without question over both Karamania and Anatolia.
