Avar-Sassanid Siege of Constantinople
Constantinople· Anatolia
While Heraclius was campaigning deep in Persia, the Sassanids coordinated with the Avars (a Central Asian nomadic power) to besiege Constantinople itself. The city was defended by Patriarch Sergius and the walls of Theodosius. The Avar assault was repelled, largely due to Byzantine naval superiority in the Bosphorus which prevented the Persian forces from crossing to join the attack.
Historical Significance
The failure to take Constantinople was the turning point. The Avar alliance collapsed, and Persia lost its last chance to deliver a knockout blow. Heraclius was now free to press his advantage.
Islamic Relevance
This siege occurred between the battles of Badr and the trench (Khandaq) in the Seerah timeline. Both the Muslims in Madinah and the Byzantines in Constantinople were facing existential sieges by superior forces — and both survived.
