Events

Arab–Byzantine War: Emperor Leo IV ("the Khazar") repulses an Abbasid invasion in Anatolia. A Byzantine expeditionary force under Michael Lachanodrakon, military governor (strategos) of the Thracesian Theme, defeats the Muslim-Arabs at the fortress city of Germanikeia in Cilicia (modern Turkey). He plunders the region and takes many captives, mostly Jacobites, who are resettled in Thrace.^[1]

A Frankish army (supported by Burgundians, Bavarians, Bretons, Lombards, and Visigoths) under king Charlemagne invades Al-Andalus (modern Spain) but is halted at Zaragoza in the thughur or frontier zone of the Emirate of Córdoba. During the retreat, Charlemagne is defeated by the Basques at Roncevaux (Pyrenees). Among those killed is Roland, governor of the Breton March, this give rise to the 11th-century epic Song of Roland. Beginning of medieval French literature.
Saxon Wars: Widukind and his close followers returns to Saxony from Denmark. He probably makes alliances with the Danes and the north-western Slav tribes. Saxon 'rebels' destroy the fortress of Karlsburg and sack Deutz (near Cologne) but are unable to cross the Rhine. They are driven back by the garrison of Koblenz, but then ambush and defeat the Frankish pursuers. Counter-attacking Frankish forces pursue the Saxons up the Lahn Valley and defeat them near Leisa.^[2]

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

Saxon raiders destroy many churches deep in Frankish territory. The Benedictine monks of Fulda Abbey (modern-day Hesse) hurriedly carry the relics of Saint Boniface over the Rhön Mountains to safety.^[3]
