731



Year 731 (DCCXXXI) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. The denomination 731 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.

Europe

 * Umayyad conquest of Gaul: Munuza, Moorish governor of Cerdagne (eastern Pyrenees), rebels against Umayyad authority. He is defeated and executed by Muslim forces under Abdul Rahman Al Ghafiqi at Urgell (Catalonia). Muslim garrisons in Septimania raid the cities Millau and Arles.
 * Ragenfrid, ex-mayor of the palace of Neustria, meets Duke Eudes of Aquitaine, to accept his rule and independence from the Frankish Kingdom. Fearing an alliance against him, Charles Martel exiles Ragenfrid's supporter Wandon of Fontenelle, and imprisons bishop Aimar of Auxerre.
 * Charles Martel leads two raids across the Loire River into the Berry region. The Franks seize and plunder Bourges (central France), but the city is immediately recaptured by Eudes of Aquitaine.

Britain

 * Autumn – King Ceolwulf of Northumbria is deposed by opponents, and forced to enter a monastery. His supporters subsequently restore him to the throne (or 732).
 * King Æthelbald of Mercia overruns a large portion of Somerset, and wrests the county from Wessex control (approximate date).

Asia

 * Battle of the Defile: An Umayyad relief army (28,000 men) is sent to Samarkand (modern Uzbekistan), which is besieged by the Turgesh. The Muslims are ambushed near the Zarafshan Range, at the Tashtakaracha Pass. The battle results in a Pyrrhic victory, with heavy casualties for the Umayyad army, halting Muslim expansion in Central Asia for almost two decades.
