Sassanian Expansion Under Chosroes II
Explore the Sassanian expansion under Chosroes II, exploiting Byzantine instability for territorial gains in Syria, Jerusalem, and Egypt.
Overview
The reign of Chosroes II marked a significant period of Sassanid expansion into Byzantine territories due to internal instability within the Byzantine Empire and external support from Maurice, his ally who was later murdered. This period saw Persian forces ravaging Syria, sacking Jerusalem in 615, and advancing as far south as Egypt and north towards Constantinople itself.
Context
During the early seventh century, both the Sassanid and Byzantine empires were experiencing significant turmoil. The Sassanian Empire was under the rule of Chosroes II, who sought to expand his territory following a weakened Byzantium due to internal strife and external threats such as Slavic and Avar incursions into the Balkans. The death of Emperor Maurice in 602 provided Chosroes with an opportunity for territorial expansion, given that the Byzantine Empire was struggling under its new ruler Phokas.
