The siege of Caesarea relates to the siege and conquest of Caesarea Maritima of the Byzantine Empire's Palaestina Prima province by the Sasanian Empire in 614 CE.
The Shah Khosrow II appointed his general Shahrbaraz to conquer the Byzantine controlled areas of the Near East. Following the victory in Antioch, Shahrbaraz conquered Caesarea Maritima, the administrative capital of the province.[1] By this time the grand inner harbor had silted up and was useless, however the Emperor Anastasius had reconstructed the outer harbor and Caesarea remained an important maritime city, providing the Sasanian Empire with access to the Mediterranean Sea.[2] While the Sasanian siege and occupation of Caesarea resulted in limited physical destruction, the socioeconomic effects were likely more significant. The later Arab conquest also devastated the city and it subsequently entered a period of decline.[3]
