Events

A Byzantine expeditionary force under Staurakios, chief minister (logothete), begins a campaign against the communities (Sclaviniae) of Greece. Setting out from Constantinople, the imperial army follows the Thracian coast into Macedonia, and then south into Thessaly, Central Greece and the Peloponnese. Staurakios restores a measure of Byzantine authority over these areas, and collects booty and tribute from the locals.

Mauregatus of Asturias, illegitimate son of the late king Alfonso I, usurps the throne after the death of his brother-in-law Silo. However, the nobility has elected Alfonso II at Adosinda's (wife of Silo) insistence, but Mauregatus assembles a large army of supporters, and forces Alfonso to flee to Álava (modern Spain). Adosinda is put in the monastery of San Juan de Pravia, where she lives out the rest of her life.
April 30 – Hildegard, wife of King Charlemagne, dies in childbirth after her ninth confinement in less than 12 years of marriage. His mother, Bertrada of Laon, dies in the summer and is buried with great ceremony beside her husband Pepin the Short, in the Abbey of St. Denis (modern-day Paris).
October – Charlemagne marries Fastrada, the 18-year-old daughter of a Frankish count named Rudolph, and makes her his queen at Worms. The probable reason behind the marriage is to solidify a Frankish alliance east of the Rhine, against the Saxons in Lower Saxony (modern Germany).
Winter – Saxon Wars: Charlemagne defeats the Saxon rebels in a three-day battle next to the Hase River, and perhaps overruns fortifications on the Wittekindsberg, before ravaging southern Saxony. A Frisian uprising against Carolingian rule is supported by Duke Widukind.^[1]
