The restoration of Tahmasp II to the Safavid throne took place in the latter part of 1729 by a series of battles fought between Nader, Tahmasp's commander-in-chief and Ashraf Hotaki. Despite nominally bringing Tahmasp to the seat of power, true authority still rested with Nader who had ever since the debacle in northern Khorasan managed to seize Tahmasp II as his vassal. As for Afghan rule, the Ghilzai Afghans were ejected from the Iranian Plateau permanently and in the following years were re-annexed by Nader whence they were once again absorbed into the Persian empire.
