Dinar - Boran

Boran — sometimes rendered Purandokht — was the first woman to rule the Sasanian Empire, ascending to the throne following the chaos of Khosrow II's execution and a rapid succession of short-lived male rulers. Her reign of roughly one year placed her in power just as the empire was hemorrhaging territory and manpower from decades of war with Byzantium. Gold dinars struck in her name are extraordinarily rare, a direct consequence of how briefly she held authority and how fractured imperial administration had become by 630.

She ruled twice, briefly, with a second stint in 631. Most surviving examples cannot be assigned with confidence to either reign.
