The truce of Kütahia, it has to be remembered, was not a permanent settlement; it was an agreement that neither Sultan nor vali put their signatures to and, moreover, its terms were to be renewed each year, giving Mehmed Ali the feeling that he had still not guaranteed for his family the secure future he was striving for. In addition, Mehmed Ali was required to pay an annual tribute to Istanbul, the amount of which was one of the most contentious issues in the years between 1833 and 1839: while the Sultan was claiming significant arrears, the Pasha refused to pay them. This issue became more acrimonious since the Pasha was convinced that the presence of Husrev as Serasker in Istanbul and his proximity to the Sultan made Mahmud particularly susceptible to his intrigues.

XREF: Connects to the earlier Kütahia claims at loc 182 and loc 252 about the annually renewable agreement leaving Mehmed Ali dependent. Builds on: "Ottoman sultan resisted Egypt's Syrian expansion with armed threats."
