Year 766 (DCCLXVI) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. The denomination 766 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

By place

Byzantine Empire

• August 25 – Emperor Constantine V publicly humiliates 19 high-ranking officials in the Hippodrome of Constantinople, after discovering a plot against him. He executes the leaders, Constantine Podopagouros and his brother Strategios, and blinds and exiles the rest.
• Autumn – Siege of Kamacha: Abbasid forces under al-Hasan ibn Qahtaba are defeated at the fortress city of Kamacha, in eastern Cappadocia (modern Turkey). A Byzantine relief army (12,000 men) forces the Abbasids to retreat into Armenia.
• Sabin, ruler (khagan) of Bulgaria, flees to the Byzantine fortress city of Mesembria, from where he escapes to Constantinople. Constantine V arranges for the transfer of Sabin's family from Bulgaria.

Abbasid Caliphate

• Baghdad nears completion as up to 100,000 labourers create a circular city about 1 or 2 km in diameter (depending on the source). In the center of the "Round City" is a palace built for Caliph al-Mansur. The capital is ringed by three lines of walls (approximate date).
