Events

Byzantine–Bulgarian War: Emperor Constantine IV is forced to acknowledge the Bulgar state in Moesia, and to pay protection money to avoid further inroads into Byzantine Thrace.^[1] Consequently, Constantine creates the Theme of Thrace of the Byzantine Empire (located in the south-eastern Balkans).^[2]
Autumn – A military revolt breaks out in the Anatolic Theme (modern Turkey). The Byzantine army marches to Chrysopolis, and sends a delegation across the straits of the Hellespont to Constantinople, demanding that the two brothers should remain co-emperors alongside Constantine IV.^[3]
September/November – Constantine IV has his brothers Heraclius and Tiberius mutilated, so they will be unable to rule. He orders that their images no longer appear on any coinage, and that their names be removed from official documentation.^[4]
Constantine IV agrees to a compromise, and persuades the army to return to their barracks in Anatolia. He invites the leaders of the rebellion to come to Constantinople and consult the Senate as to how to implement the terms. On their arrival, he arrests the leaders and has them hung at Sycae.^[5]

January 9 – Twelfth Council of Toledo: King Erwig of the Visigoths initiates a council, in which he implements diverse measures against the Jews. Laws against violence to slaves are suppressed.

A Muslim Arab army led by Uqba ibn Nafi reaches Morocco, before being forced back into Cyrene by the Berbers.^[6]
Armenians, Albanians, and Iberians rise in rebellion against the Umayyad Caliphate (approximate date).

January 10 – Pope Agatho dies at Rome of plague after a 2½-year reign, in which he has persuaded Constantine IV to abolish the tax heretofore levied at the consecration of a newly elected pope.
September 16 – The Sixth Ecumenical Council (see 680) ends at Constantinople. The council reaffirms the Orthodox doctrines of the Council of Chalcedon in 451, and condemns monothelitism.^[8]
