By place

Byzantine Empire

• Battle of Berzitia: The Bulgarian ruler Telerig sends a small raiding army to strike into the southwest of Macedonia, and capture Berzitia. Emperor Constantine V is informed about this raid by his spies in Pliska, and assembles an enormous force. He surprises the Bulgarians, who did not expect to find a Byzantine army there, and defeats them decisively. The Bulgars suffer heavy losses.
• Telerig sends a message to Constantine V, stating that he is going to flee in exile to Constantinople. In exchange, he asks the emperor to reveal the spies to his associates in Pliska for their own safety. Constantine sends the Bulgarian government a list of the spies; however, Telerig executes them all, and eliminates the Byzantine spy network within his government.

  Europe

• King Charlemagne conquers the Lombard Kingdom, and establishes Frankish rule in Pavia, Venetia, Istria, Emilia, Tuscany, and Corsica. Charlemagne visits Rome; he confirms the Donation of Pepin while insisting on his own sovereignty. Pope Adrian I grants him the title of patrician. Charlemagne puts down immediate insurrections in Friuli.
• June - King Desiderius surrenders the independence of the Lombards to the Franks, and is exiled to Corbie Abbey. Charlemagne annexes northern Italy as a sub-kingdom, and takes the title of Rex Langobardorum. Some Lombards flee south to Benevento, which remains independent; Duke Arechis II retitles himself "Prince of Benevento".
• Saxon Wars: Saxon raiders ravage much of northern Hesse, and burn the abbey at Fritzlar, putting the abbot and monks to the sword. Charlemagne hurriedly returns to Austrasia, assembles local troops, and recaptures Eresburg, before the approach of winter halts further operations.
• King Aurelius dies after a 6-year reign, and is succeeded by his cousin-in-law Silo, as ruler of Asturias.

  Britain

• Unrest in the Northumbrian Church appears to lead to the expulsion of King Alhred, who is driven from his capital York. He sails from Bamburgh into exile amongst the Picts, where he is received by King Ciniod I. He is replaced by Æthelred I, the 11-year-old son of the late king Æthelwald Moll.
• King Offa of Mercia subdues the Anglo-Saxon kingdoms of Kent and Wessex.

Astronomy

• A 1.2% growth of carbon-14| concentration recorded in tree rings, along with corresponding spikes of Chlorine-36| and Beryllium-10| recorded in ice cores, suggests that a very strong solar storm may have hit Earth in either 774 or 775.
