Regarded as the final prominent ruler of pre-Islamic Iran, Khosrow II held power over the Sasanian Empire from 591 until 628. His reign marked a turbulent era defined by extensive military expansion against the Eastern Roman Empire, internal domestic struggles against various usurpers, and a eventual catastrophic collapse that preceded the rise of the Islamic conquest.
Early Career and Accession
Born in 570 in Ctesiphon, Khosrow II was the son of Hormizd IV and a noblewoman from the House of Ispahbudhan. Before ascending the throne, he served as the governor of Partaw in Caucasian Albania, where he successfully incorporated the Kingdom of Iberia into the Sasanian Empire. He also functioned as the governor of Arbela in Upper Mesopotamia. In 590, a palace coup led by his uncles, Vistahm and Vinduyih, resulted in the blinding and murder of Hormizd IV, elevating Khosrow to the throne.

The stability of his early reign was immediately challenged by the general Bahram Chobin, who rebelled after being disgraced by Hormizd IV. Bahram, claiming descent from the Parthian dynasty, challenged the legitimacy of the Sasanian rulers. After his forces were defeated in battle near the Nahrawan Canal, Khosrow II fled to Byzantine territory with his uncles and a small retinue of nobles. He subsequently regained his throne in 591 with significant military support from the Eastern Roman emperor Maurice.
Military Campaigns and Decline
Khosrow II initiated a major war against the Eastern Roman Empire in 602, justifying the aggression as a retaliation for the murder of his ally, Maurice. His armies captured vast territories in the Middle East, earning him the epithet 'Parviz', or the Victorious. However, the failed Siege of Constantinople in 626 and the subsequent counterattack by the Roman emperor Heraclius depleted the Sasanian heartland. Dissatisfaction among feudal families led to his deposition and execution by his son, Kavad II, in 628.
Cultural Legacy
Beyond his political and military history, Khosrow II occupies a central position in Persian literature. Authors such as Ferdowsi in his epic Shahnameh and Nizami Ganjavi in his narrative poem Khosrow and Shirin crafted accounts of his life. These literary works depict him as a quintessential monarch and lover, specifically immortalizing his lengthy courtship and marriage to the Aramean princess Shirin.
