By place

Byzantine Empire

• Spring – The Venetian dukes change sides again, submitting to King Pepin, under the authority of his father Charlemagne, who then proceeds to take Venice. Emperor Nikephoros I sends a Byzantine fleet to Dalmatia, prompting Pepin to withdraw to the mainland. A legate is dispatched to Venice, where he deposes the turncoat dukes, before continuing on to Aachen, to negotiate a peace with Charlemagne. Charlemagne recognises Byzantine dominance over Venice and Dalmatia in the Adriatic Sea.
