Events

By place

Europe

• Umayyad conquest of Gaul: Muslim forces under Anbasa ibn Suhaym al-Kalbi (governor of Al-Andalus) capture the fortified town of Carcassonne, which has been under siege (see 720), as well as Nîmes in Septimania (the latter without resistance).^[1]
• Summer – In 725, al-Samh's successor, Anbasa ibn Suhaym al-Kalbi, moved against Gothic nobles resisting surrender. The city of Carcassonne was besieged and its Gothic ruler forced to cede half of his territory, pay tribute, and make an offensive and defensive alliance with Muslim forces. The Gothic rulers of Nîmes and the other resisting Septimanian cities also eventually fell under the sway of the Umayyads.^[2]
• Duke Eudes of Aquitaine seeks an alliance with Munuza, governor of Cerdagne (eastern Pyrenees), currently in rebellion against the central Umayyad government at Córdoba in Andalusia (probably not cemented until 729).^[3]

• King Liutprand puts Corsica, nominally under Byzantine authority, under Lombard government, defending it from Muslim raids (approximate date).
