Hormizd IV, born in the year five hundred forty, ascended to the throne as the King of Kings of Sasanian Iran in five hundred seventy-nine, following in the footsteps of his father, Khosrow I. His lineage included a Khazar princess as his mother, which added a unique dimension to his royal heritage.
During his reign, which lasted until five hundred ninety, Hormizd IV was known for his controversial policies. He took drastic measures against the high aristocracy and the Zoroastrian priesthood, opting instead to support the landed gentry, known as the dehqans. His rule was characterized by relentless warfare, particularly against the Byzantine Empire to the west, a conflict that had roots in his father's era. Meanwhile, in the east, the Iranian general Bahram Chobin achieved significant victories against the Western Turkic Khaganate.
Hormizd IV's reign also saw the dissolution of the Chosroid dynasty in Iberia, which he successfully integrated into the Sasanian Empire after securing the support of the Iberian aristocracy. However, his relationship with Bahram Chobin soured due to jealousy over the general's successes, leading to Bahram's disgrace and subsequent rebellion, which ignited the Sasanian civil war from five hundred eighty-nine to five hundred ninety-one.
Ultimately, Hormizd IV's reign came to a tragic end when he was deposed and killed by discontented nobles, paving the way for his son, Khosrow II, to take the throne. Despite being viewed as a tyrant by contemporary sources, modern historians offer a more nuanced perspective, recognizing Hormizd IV as a ruler who, albeit overambitiously, sought to uphold his father's legacy while maintaining a degree of religious tolerance.
