But in 1544, the Özbegs again succeeded in entering the town and plundering and murdering there. The year 1589 was a disastrous one for Mashhad. The Shaybanid ‘Abd al-Mu’min after a four months’ siege forced the town to surrender. Shah Abbas I, who lived in Mashhad from 1585 till his official ascent of the throne in Qazwin in 1587, was not able to retake Mashhad from the Özbegs till 1598.
