The Caliph El-Mustain was then proclaimed sultan, but after some months he was dethroned and his former prime minister, Sheikh Mahmudi, took over the reins of government (November, 1412). Although Sheikh had obtained the throne of Egypt so easily, he experienced great difficulty in obtaining the recognition of the emirs. Newruz, Governor of Damascus, in league with the other governors, made a determined resistance, and he was obliged to send a strong army into Syria to put down the rebels. Newruz, after suffering one defeat, threw himself into the citadel of Damascus and capitulated, when Sheikh had sworn to keep the terms of the capitulation. Newruz's ambassadors, however, had not a sufficient knowledge of Arabic to perceive that the oath was not binding, and when Newruz, trusting to this oath, appeared before Sheikh, he was immediately thrown into chains, and afterwards murdered in prison because the cadis declared the oath was not binding. In the next year (1415) Sheikh was obliged to make another expedition against Syria to re-conquer some of the places of which the smaller princes had taken possession during the civil war. One of these princes was the Prince Muhammed of Karaman, who had taken the town of Tarsus. Sheikh was summoned by Muhammed's own brother to overcome him, which he easily succeeded in doing. Many other princes were forced to submit, and finally the town of Malatia, which the Turcoman Husain had stormed, was recaptured. The war against Husain and the Prince of Karaman was to have been continued, but Sheikh was forced to return home, owing to a wound in his foot. As soon as certain misunderstandings between Sheikh and Kara Yusuf had been cleared up, another army was despatched into Asia Minor, for Tarsus had been recaptured by the Prince of Karaman, who had driven out the Prince of Albustan, whom Sheikh had installed. Ibrahim, the sultan's son, took command of this army, and occupied Caasarea, Nigdeh, and Kara-man. Whilst he was occupied in the interior of Asia Minor, the Governor of Damascus had defeated Mustapha, son of the Prince of Karaman, and the Prince Ibrahim of Ramadhan, near Adana, which latter town, as well as Tarsus, he had re-conquered. The Prince of Karaman, who now advanced against Caasarea, suffered a total defeat. Mustapha remained on the field of battle, but his father was taken prisoner and sent to Cairo, where he lingered in confinement until after the death of the sultan.
