Shahrbaraz, was shah (king) of the Sasanian Empire from 27 April 630 to 9 June 630. He usurped the throne from Ardashir III, and was killed by Iranian nobles after forty days. Before usurping the Sasanian throne he was a spahbed (general) under Khosrow II (590–628). He is furthermore noted for his important role during the climactic Byzantine–Sasanian War of 602–628, and the events that followed afterwards.
The Byzantine–Sasanian War of 602–628 was the final and most devastating of the series of wars fought between the Byzantine / Roman Empire and the Sasanian Empire of Iran. The previous war between the two powers had ended in 591 after Emperor Maurice helped the Sasanian king Khosrow II regain his throne. In 602 Maurice was murdered by his political rival Phocas. Khosrow declared war, ostensibly to avenge the death of the deposed emperor Maurice. This became a decades-long conflict, the longest war in the series, and was fought throughout the Middle East: in Egypt, the Levant, Mesopotamia, the Caucasus, Anatolia, Armenia, the Aegean Sea and before the walls of Constantinople itself.
The 600s decade ran from January 1, 600, to December 31, 609.
The Avar–Byzantine wars were a series of conflicts between the Byzantine Empire and the Avar Khaganate. The conflicts were initiated in 568, after the Avars arrived in Pannonia, and claimed all the former land of the Gepids and Lombards as their own. This led to an unsuccessful attempt to seize the city of Sirmium from Byzantium, which had previously retaken it from the Gepids. Most subsequent conflicts came as a result of raids by the Avars, or their subject Slavs, into the Balkan provinces of the Byzantine Empire.
