Year 775 (DCCLXXV) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. The denomination 775 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.


By place[edit]

Byzantine Empire[edit]


  • 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.[1]
  • 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.[2]
  • 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.[3]
  • The German city of Giessen (Hesse) is founded.


Arab Caliphate[edit]

Abbasid caliph al-Mansur was succeeded by his heir and son Al-Mahdi, on 6th October 775.
  • At around this time, Baghdad becomes the largest city in the world, taking the lead from Chang'an, capital of China.[5]
