The Persian Shah Khosrau 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. By this time the grand inner harbor had silted up and was useless. However the Emperor Anastasius had completed a reconstruction of the outer harbor, consequently Caesarea was an important maritime city, providing the Persian Empire with access to the Mediterranean Sea. While the Persian siege and occupation of Caesarea resulted in limited physical destruction. The socioeconomic affects where likely more significant. The Arab conquest would also devastate the city. The city subsequently entered a period of decline.
