 The Mamluk sultan Qansuh al-Ghawri was warned by the Ottoman sultan Selim I that al-Ghawri was providing the envoys of the Ismail I safe passage through Syria on their way to Venice and harboring refugees.To appease him, al-Ghawri placed in confinement the Venetian merchants then in Syria and Egypt, but after a year released them.After the Battle of Chaldiran in 1514, Selim I attacked the Dulkadirids, an Egyptian vassal, and sent their chief's head to al-Ghawri.
