Events

Byzantine Empire

  • Summer Emperor Leo III secures the Byzantine frontier, by inviting Slavic settlers into the depopulated districts of the Thracesian Theme (western Asia Minor). He undertakes a set of civil reforms, and reorganizes the theme structure in the Aegean region. Leo's 2-year-old son Constantine V is associated on the throne, and married to Tzitzak, daughter of the Khazar ruler (khagan) Bihar.

Europe

Britain

Arabian Empire

  • Umayyad conquest of Transoxiana: The first Turgesh attack on Muslim-Arabs in Transoxiana leads to the siege and relief of the Umayyad garrison at the fortress of Qasr al-Bahili, near Samarkand (or 721).
  • Yazid ibn al-Muhallab, former governor of Iraq, revolts and is defeated at Basra, by Umayyad forces under Al-Abbas ibn al-Walid and Maslama ibn Abd al-Malik. He is arrested and later executed.
  • February 10 Caliph Umar II is poisoned by a servant, and dies in Aleppo (Syria) after a 3-year reign. He is succeeded by his cousin Yazid II.
  • 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 limestone bedrock beneath. As a consequence of this, more than 500 homes are destroyed (approximate date).

Americas

  • The Third Tikal-Calakmul War begins.

Literature

  • The Nihon Shoki (日本書紀), one of the oldest history books in Japan, is completed under the editorial supervision of Prince Toneri, and with the assistance of Ō no Yasumaro.[2]

Religion

  • 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.

Births

  • Baizhang Huaihai, Chinese Zen Buddhist monk (d. 814)
  • Bernard, Frankish nobleman (approximate date)
