By place

Byzantine Empire

• After spending nearly a decade with the Khazars (a Turkic tribe which controls a Steppe empire), the deposed emperor Justinian II flees from his exile at Cherson (Crimea). He escapes with help from Busir, ruler (khagan) of the Khazars, who marries him to his sister Theodora.

• Autumn Emperor Tiberios III tries to bribe Busir and dispatches two Khazar officials, Papatzys and Balgitzin, to kill Justinian. Warned by his wife, he flees to the Bulgar Khanate, securing the assistance of the Bulgarian ruler Tervel, in exchange for financial considerations.

• Arab–Byzantine War: A Byzantine expeditionary force under Heraclius (brother of Tiberios III) defeats and destroys an Umayyad army (10,000 men) at Sisium (modern Turkey) under Yazid ibn Hunayn, killing most and leading the others off in chains to Constantinople.
