[1] In 1619, with the help of the Safavid troops and the Safavid-appointed ruler in Tiflis, Semayun Khan (Simon II), Zurab managed to drive his elder brother Bahadur out of Bazaleti.
[2] Receiving further aid from them, he started to conduct raids against the people of Mtiuleti and the Khevi; he managed to submit these countries, and became notoriously powerful.
[4][5] When in 1624 Safavid king Abbas I (r. 1588–1629) decided to marry his granddaughter to Semayun Khan, the Safavid ruler of Kartli, Sohrab Eristavi and Abd-ol-Ghaffar Amilakhori entertained the guests in the third term of the wedding party on the order of Murav Beg.
[8] However, in 1630 Zurab was killed on the orders of Teimuraz I, shortly after the king had instigated the duke to murder the Safavid-sponsored ruler of Kartli, Semayun Khan.
[9][2] Zurab was succeeded as duke (eristavi) of Aragvi by his younger brother, known by his dynastic name of David I.
