Events

April 24 – Emperor Leo IV ("the Khazar") appoints his 5-year-old son Constantine VI co-ruler of the Byzantine Empire. This leads to an uprising, led by one of Leo's half-brothers, Caesar Nikephoros, the second son of former emperor Constantine V. The revolt is quickly suppressed. Fortunately for Nikephoros, his only punishment is to be stripped of his titles, while the rest of the conspirators are blinded, tonsured, and exiled to Cherson (southern Crimea) under guard.<ref>The Chronicle of Theophanes Anni Mundi 6095–6305 (A.D. 602–813): Tr.
