Hormizd VI was a Sasanian prince who ascended to the throne during a tumultuous period in the empire's history, ruling from six hundred thirty to six hundred thirty-two. His reign was marked by the aftermath of the overthrow and execution of his grandfather, Khosrow II, which ignited a civil war and led to a succession of monarchs with notably brief reigns.
Before Hormizd VI's rise, the throne was briefly occupied by Shapur-i Shahrvaraz, who was deposed by the influential magnate Farrukh Hormizd. In a twist of fate, Hormizd VI was proclaimed king in Nisibis by the troops of the prominent general and usurper, Shahrbaraz, shortly after the Sasanian princess Azarmidokht was raised to the throne in Ctesiphon in six hundred thirty.
Hormizd VI managed to maintain his position for approximately two years in Nisibis. However, his reign came to an abrupt end when he was overthrown by the very troops that had once supported him. Following his downfall, Yazdegerd III, another grandson of Khosrow II, emerged as the sole ruler of the Sasanian Empire, backed by the support of the nobles.
