Safavid Empire
His successor, Abbas I, initiated a Reconquest, with the Uzbeks invading Khorasan first. By 1599, Abbas had conquered not only Herat and Mashhad, but had moved as far east as Balkh. This would be a short-lived victory and he would eventually have to settle on controlling only some of this conquest after the new ruler of the Khanate of Khiva, Baqi Muhammad Khan attempted to retake Balkh and Abbas found his troops were still no match for the Uzbeks. By 1603, the battle lines had stabilized, albeit with the loss of the majority of the Persian artillery. Abbas was able to hold onto most of Khorassan, including Herat, Sabzevar, Farah, and Nisa.
