  • 613Battle of Antioch: Heraclius mobilises a Byzantine expeditionary force to Antioch (Syria), but is completely defeated outside the city by the Persians.

  • 617Byzantine-Sassanid War: The Persian army under Shahin Vahmanzadegan conquers Chalcedon in Anatolia, and reaches the Bosporus, threatening Constantinople.

  • 623Byzantine–Sassanid War: Emperor Heraclius invades Armenia, leaving his son Constantine (age 11) and co-regent Bonus to defend Constantinople against the Persians still at Chalcedon (modern Turkey). He sails with 5,000 reinforcements to join the Byzantine army at Trapezus.
