Introduction to the Byzantine-Sasanian War of 602-628

The Byzantine-Sasanian War of 602-628 was a significant conflict that occurred between the Byzantine Empire and the Sasanian Empire in the early 7th century. This war was one of the most prolonged and devastating conflicts in the history of the Eastern Roman Empire, also known as the Byzantine Empire.

The causes of the war can be traced back to various factors. Both empires were longstanding rivals vying for supremacy in the region. Additionally, religious tensions played a role, as the Byzantine Empire was predominantly Christian, while the Sasanian Empire adhered to Zoroastrianism. This religious divide further fueled animosity and territorial disputes between the two powers.

Both empires were also dealing with internal challenges that affected their stability and led to the outbreak of the war. The Byzantine Empire was facing financial difficulties and internal strife, while the Sasanian Empire was grappling with succession issues after the assassination of its ruler, Khosrow II.

The war began in 602 when the Byzantine Emperor, Phocas, refused to pay tribute to the Sasanian Empire. This prompted Khosrow II to launch a military campaign into Byzantine territory, aiming to depose Phocas and seize control of the Byzantine Empire. The initial clashes between the two powers resulted in territorial gains for the Sasanians, pushing deep into Byzantine territory.

The Byzantine-Sasanian War of 602-628 had far-reaching consequences, not only for the immediate participants but also for the broader region. It weakened both empires, leaving them vulnerable to subsequent invasions by outside forces. The prolonged conflict also led to social and economic upheaval, affecting the wellbeing of the civilian populations in both empires.
