Tahmasp II
After the coronation of the Safavid prince Tahmasp II as shah of Iran in 1730, Nader Shah married one of the latters sisters, while his eldest son Reza Qoli Mirza Afshar married another of his sisters, Fatimeh Soltan Begom. In March 1734, Shahrokh was born from the union of Reza Qoli Afshar and Fatimeh Soltan Begom. The news reached the court in Isfahan on the day of Nowruz (Iranian New Year), with Nader Shah subsequently appointing Shahrokh the ruler of the city of Herat. With the birth of the half-Safavid Shahrokh, Nader Shah was able to bolster his legitimacy.
