The 740s decade ran from January 1, 740, to December 31, 749.

• Battle of Akroinon: Following the disastrous Battle of Sebastopolis (see 692), Emperor Leo III has largely confined himself to a defensive strategy, while the Umayyad armies regularly launch raids into Byzantine-held Anatolia.^[1] Caliph Hisham ibn Abd al-Malik assembles an expeditionary force (90,000 men) under his son Sulayman ibn Hisham. One of these armies, 20,000 men strong under Abdallah al-Battal, is defeated at Akroinon (modern-day Afyon) by the Byzantines, led by Leo and his son, the future emperor Constantine V. About 6,800 Muslim Arabs, however, resist and manage to conduct an orderly retreat to Synnada (Phrygia).^[2]

All of them are successful, submitting the Islands and returning with much wealth from the spoils of war.

• King Eadberht of Northumbria marches his army north to attack the Picts. King Æthelbald of Mercia takes advantage of his absence, and ravages the city of York. Internal struggles re-emerge in Northumbria with the murder of Eardwine, probably the son of the late usurping king Eadwulf I.^[5][6]
