Gokcheh Sultan Ziyadoghlu Qajar (Persian: گکچه سلطان زیاداوغلی قاجار), better known as Shahverdi Sultan (شاهوردی سلطان), was a Safavid military leader of Turkoman origin, who served as the governor of Karabakh and Ganja during the reign of king Tahmasp I (r. 1524–1576).
[2] In 1547, Shahverdi Sultan was appointed as the guardian (lala) of the Safavid prince Ismail Mirza and co-governor of Shirvan with the latter.
The following year, during the Ottoman–Safavid War of 1532–1555, Shahverdi Sultan and Ismail Mirza, with an army of 7,000 soldiers, sacked the important neighboring Ottoman stronghold of Kars.
[3] In 1554, Shahverdi Sultan was appointed governor of the Karabakh beglerbeylik and of its administrative center, Ganja, by Tahmasp I.
[4][2] A year later, in 1555, he was immediately dispatched by Tahmasp I to secure the eastern Georgian kingdoms of Kartli and Kakheti, which had been recognized as Iranian domains per the ratified Peace of Amasya with the Ottoman Empire.
