  • 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 limestone bedrock 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.

  • Umayyad conquest of Gaul: Muslim raiders under Abdul Rahman al-Ghafiqi, current governor of Septimania, devastate Avignon, Viviers, Valence, Vienne and Lyon (approximate date).
  • Marcello Tegalliano dies after a 9-year reign.
  • 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.
  • Seismic activity in the Mediterranean Sea: The volcanic island of Thera erupts, while the city of Jerash (in present-day Jordan) suffers a major earthquake.
