The Grand Vizier and the Austrian front Serdar-ı Ekrem Lala Mehmed Pasha returned to Istanbul while negotiations were being held at Zitvatorok to sign a peace agreement with Austria.
Captain-Derya Sultan, who was a relative of Ahmed I, was making suggestions to send the Grand Vizier to the Iran front as serdar.
Sultan Ahmed was also very determined to make Lala Mehmed Pasha the Serdar of Iran.
Lala Mehmed Pasha, who came to peace, stated that the Austrian war had still not been settled and that it was not right to go to the Iran expedition for this.
Vizier-i Azam Lala Mehmed Pasha, who was very sorry for this, suffered a stroke and died a few days later.
British Ambassador to Istanbul Sir Henry Lello reports that Derviş Mehmet Pasha took the surplus income of the foundations on the pretext of the shortage of treasury and that he had the rich Jews collect silver and jewelry with the promise to pay the price later.
