Muhammad Shaybani Khan’s Shaybanid Uzbeks captured Herat, establishing a strong Uzbek foothold in Khorasan and setting up a recurring Safavid–Uzbek frontier struggle over the province’s major cities.
Shah Ismail I’s forces defeated and killed Muhammad Shaybani Khan at Merv, reversing Uzbek gains and enabling Safavid reassertion in Khorasan; the battle became a foundational Safavid victory in the eastern wars.
A Safavid army operating with Babur (Timurid/Mughal) suffered defeat at Ghazdewan (Ghijduvan). The setback checked Safavid influence beyond the Oxus and helped trigger renewed Uzbek pressure into Khorasan.
Following the post-Ghazdewan Uzbek advance, Shaybanid forces successfully besieged and took Herat again, extending their reach across Khorasan and increasing pressure on nearby centers such as Mashhad.
Soon after retaking Herat, Uzbek contingents advanced on and captured Mashhad, underscoring how the war often hinged on controlling a small number of fortified cities that anchored Khorasan’s administration and revenue.
Shah Tahmasp I defeated a major Uzbek incursion at the Battle of Jam (near Zurabad in Khorasan). The victory showcased Safavid tactical adaptation (including gunpowder-era methods) and temporarily blunted Uzbek momentum in the east.
After Shah Tahmasp I’s death, Uzbek forces again penetrated Khorasan in a significant raid that reached Mashhad and nearby districts. The episode reflects how Safavid succession crises repeatedly created openings for Uzbek offensives.
Amid late-16th-century Safavid instability, the Uzbeks under the Shaybanid state recovered Herat, beginning a decade-long period in which the city remained in Uzbek hands and Khorasan’s defense became a central Safavid strategic problem.
Shah Abbas I won a decisive victory against the Uzbeks at Herat, recapturing the city and consolidating Safavid recovery of Khorasan. The campaign is widely treated as a turning point that secured the eastern frontier before renewed western wars.
Abbas I attempted an ambitious winter offensive toward Balkh/Transoxiana, but logistical difficulties forced a retreat and the loss of much artillery. The failure underscored the constraints of sustaining large operations beyond Khorasan’s core.
With the western front temporarily stabilized later in Abbas I’s reign, Safavid forces were ordered to assemble at Nishapur for operations on the eastern frontier. This mobilization reflects the continued need to deter or answer Uzbek pressure even after 1598.
Safavid forces captured Kandahar from the Mughals. While not an Uzbek battle, the fortress’ recovery reshaped the broader military balance around Khorasan by improving Safavid strategic depth on the empire’s eastern approaches.
