Events

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.^[2]
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.^[3]^[4]
Arab–Byzantine War: A Byzantine expeditionary force under Heraclius (brother of Tiberios III) is defeated and destroyed by an Umayyad army (10,000 men) at Sisium (modern Turkey), killing most and leading the rest off in chains to Damascus.^[3]^[5]

King Æthelred I abdicates the throne after a 30-year reign and becomes an abbot at Bardney (Lincolnshire). He is succeeded by his nephew Cenred (Coenred), a son of the late king Wulfhere, who becomes ruler of Mercia.
December 14 – King Aldfrith of Northumbria dies after a 20-year reign. His throne is seized by Eadwulf I, of unknown descent. Wilfrid travels to Driffield to support Eadwulf, but his advances are rejected (approximate date).

Arab conquest of Armenia: The Muslim Arabs under Abdallah ibn Abd al-Malik (a son of caliph Abd al-Malik ibn Marwan) invade Armenia and subdue the anti-Arab revolt along with his uncle Muhammad ibn Marwan.^[3]^[5]
Winter – Abdallah ibn Abd al-Malik is recalled from Armenia to serve as governor of Egypt. He requires that government business be done in Arabic instead of Coptic. His tenure is marred by famine and corruption.

Emperor Tridu Songtsen dies in battle, and is succeeded by his mother Khri ma lod, who becomes de facto ruler of the Tibetan Empire. She begins a massive expansion into the Tarim Basin and Northern China.
