The Umayyad Caliphate reaches its greatest extent in Spain, controlling all of it except a small region in the north controlled by the Kingdom of Asturias.
Asia
In the Chinese capital of Chang'an, the walls of a gated city ward collapse during the night, which unexpectedly forms a large pool out in the open. This is most likely caused by a sinkhole created when ground water eroded the limestonebedrock beneath. As a consequence of this, more than 500 homes are destroyed (approximate date).
Contact between the Welsh Church and Yvi of Brittany is the last known link between two Celtic countries. After this, each nation goes its own separate way (approximate date).
Astronomy
A second series of gravitational interactions with Saturn, the second since 1664 BC, once again force the Centaur (minor planet)Chiron into a new orbit, shifting it from orbiting in the edges of the Solar System to orbiting near the inner regions.
Tervel, ruler (khagan) of the Bulgarian Empire, dies after a 21-year reign. He is succeeded by Kormesiy, possibly a son of Tervel, who is co-ruler and a descendant of the royal Dulo clan.
Rains and heavy storms around the southern seaport of Yangzhou destroy over 1,000 ships and boats in the Grand Canal, during the Tang dynasty (approximate date).
King Ine of Wessex attempts a takeover of Dumnonia, but his armies are crushed, and he is forced to withdraw. Queen Æthelburg, wife of Ine, destroys the royal castle of Taunton, to prevent its seizure by rebels under Ealdbert.[6]
King Liutprand puts Corsica, nominally under Byzantine authority, under Lombard government, defending it from Muslim raids (approximate date).
Britain
The exiled prince Ealdbert, possibly a nephew of King Ine of Wessex looking for recognition as his heir, seeks sanctuary in Sussex. Ine attacks the South Saxons and kills Ealdbert.
Emperor Leo III issues a series of edicts banning the veneration of images (726–729), and launching the iconoclastic controversies.[12] Most of the clergy – particularly in Italy and Greece – are opposed to these edicts with uncompromising hostility, and in the western parts of the Byzantine Empire the people refuse to obey his religious reforms.
Uprising in Venice against Byzantium: The cause of mass unrest is the iconoclastic decrees of Emperor Leo III. A few days later, political demands are put forward for wide autonomy within the Byzantine Empire and the right to appoint the ruler of the region (Doge). The rebels elect Orso Ipato the Doge of Venice. Desiring to preserve the proceeds of the treasury from the second most important port of the Byzantine Empire, and not having the resources to cope with a well-fortified and armed region, Byzantium agrees with all the requirements put forward. Orso Ipato is recognised by Leo III, who gives him the title hypatos. The Venetian fleet, led by Orso Ipato, frees Ravenna from the Lombards and restores the power of the Byzantine governor there.
A revolt breaks out in Italy against Leo's Iconoclasm; this results in the independence of the Exarchate of Ravenna, after part of a Byzantine invasion force is lost in a storm in the Adriatic Sea, and the remainder of Byzantine troops are repulsed.
In Denmark, construction of the Kanhave Canal across the island of Samsø is completed. Although the canal is only about 500 metres long, it is one of the largest engineering projects undertaken in Denmark during the Early Middle Ages.[21]
Siege of Kamarja: A small Arab garrison defends the fortress of Kamarja against the Turgesh for 58 days, ending with a negotiated withdrawal to Samarkand.
