Byzantine Empire
  • Battle of Berzitia: The Bulgarian ruler (khagan) Telerig sends a small raiding army (12,000 men) 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 (80,000 men). He surprises the Bulgarians, who did not expect to find a Byzantine army there, and defeats them with 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.[11]

Astronomy
  • A 1.2% growth of carbon-14 concentration recorded in tree rings suggests that a very strong solar storm may have hit the earth in either 774 or 775. A team of German scientists believes it was instead caused by a gamma ray burst, which thankfully took place far away enough from the Sun to spare the earth's biosphere and not trigger a mass extinction event.[13]

  • Saxon Wars: King Charlemagne holds a major assembly at Quierzy (Northern France). He leads a Frankish army into Saxony to retake the castrum of Syburg (near Dortmund), then rebuilds and garrisons fortified Eresburg. He reaches the Weser at a place called Braunsberg, where the Saxons stand for battle, but are defeated when Frankish troops cross the river.[14]
  • Westphalian Saxons, probably commanded by Widukind, cross the Weser and fight an inconclusive battle at Hlidbeck (modern-day Lübbecke). Charlemagne claims victory, but perhaps in reality suffers a setback. He reunites his forces and inflicts a real defeat upon the Saxons, seizing considerable booty and taking hostages, though Widukind escapes.[15]
  • Autumn – Charlemagne retakes the Hellweg (main corridor) along the Lippe Valley, establishing communications between Austrasia, Hesse and Thuringia. It is used as a trade route under Frankish supervision.[16]
  • The German city of Giessen (Hesse) is founded.

  • Unrest in Northumbria leads to King Æthelred I ordering the execution of three of his dukes. This considerably weakens his position (approximate date).
