Ottoman Sultan
Bayezid II was still engaged in Europe when there suddenly in 1501 appeared a new ground of hostility with
Egypt. It arose out of the relations of the two kingdoms with the
Safavid dynasty in
Persia. Shah
Ismail I of Persia was a
Shia Muslim who had embarked on a war with the
Sunni Ottoman Sultanate over the
Caucasus and religious differences. Many
Sufi sects had been arrested or exiled by Sultan Bayezid II as dangerous to his rule; and Shah Ismail I's request, that instead they should be allowed free transit into Europe across the
Bosporus, was rejected. Upon this, Shah Ismail I sent an Embassy to the
Venetians via
Syria inviting them to join his arms and recover the territory taken from them by the
Porte. Sultan Bayezid II, angry with the
Mamluk Sultan Al-Ashraf Qansuh al-Ghuri, complained bitterly that this Embassy had been suffered to pass through Syria. To appease him, Al-Ashraf Qansuh al-Ghuri placed in confinement the
Venetian merchants then in Syria and Egypt. And although, fearing reprisals from Venice, he after a year released them, yet the relations between Egypt and the Porte remained peaceful for a time. On the succession, however, of
Selim I to the throne of Ottoman Sultanate, things took a very different turn. Not only had the attitude of Shah Ismail I become more threatening, but Sultan Selim I himself was more of the warrior than his father. Selim I set out against him, and the
Battle of Chaldiran was fought near
Tabriz on 23 August 1514. The fanaticism of the Sufis, which led even to their women joining in the combat, failed against the cavalry and artillery of the Turks, and Ismail after a disastrous defeat fled and escaped. Selim I, his provisions failing, returned westward and spent the winter at
Amasia. In the spring taking the field again, he attacked the bey of
Dulkadirids who as Egypt's vassal had stood aloof, and sent his head with tidings of the victory to Mamluk Sultan Al-Ashraf Qansuh al-Ghuri. Selim I later overran
Diyarbakır and
Iraq, taking Roha,
Nineveh, the
Nineveh Plains,
Nisibin,
Mosul and other cities. Secure now against Shah Ismail I, a larger project dawned upon Selim I; it was the conquest of Egypt, and the fact that the invasion must be made from Syria. With no anxieties toward the North, he could now safely make the advance, and so in the spring of 1516 CE he drew together for this end a great and well-appointed army; and with the view of deceiving Egypt, represented his object to be the further pursuit of Shah Ismail I. ==Fall of the Mamluk Sultanate==
