Perso-Turkic war of 627–629
The Perso-Turkic war of 627–629 was the third and final conflict between the Sasanian Empire and the Western Turkic Khaganate. Unlike the previous two wars, it was not fought in Central Asia, but in Transcaucasia. Hostilities were initiated in 627 AD by Tong Yabghu Qaghan of the Western Göktürks and Emperor Heraclius of the Byzantine Empire. Opposing them were the Sassanid Persians, allied with the Avars. The war was fought against the background of the last Byzantine-Sassanid War and served as a prelude to the dramatic events that changed the balance of powers in the Middle East for centuries to come.
