Events
By place
Byzantine Empire
- June 22 – Battle of Versinikia: The Bulgars led by Krum, ruler (khan) of the Bulgarian Empire, defeat emperor Michael I near Edirne (modern Turkey). The Byzantine army (26,000 men) is destroyed by a counter-attack of Bulgarian heavy cavalry while trapped in the valley. Krum captures the Byzantine camp and a rich prize including gold and weaponry.
- July 11 – Michael I, under threat by conspiracies, abdicates in favor of his general Leo the Armenian and becomes a monk (under the name Athanasius). His sons are castrated to prevent them succeeding the Byzantine throne, and relegated into monasteries. One of them, Niketas (renamed Ignatius), eventually becoming a patriarch of Constantinople.
- July 17 – Krum reaches Constantinople and sets his camp outside the walls. He is given an invitation, and a promise of safe conduct to meet Leo V. Krum sets out unarmed for the capital with only a small escort, but is ambushed and manages to escape. After this unsuccessful Byzantine murder attempt, the Bulgars ravage much of Eastern Thrace.[1]
- Autumn – Siege of Adrianople: Krum captures Adrianople—one of the most important Byzantine fortresses in Thrace—after being attacked with siege engines. The garrison is forced to surrender due to starvation. On order of Krum the population and the surrounding area (numbering about 10,000) is transferred to Bulgarian territory north of the Danube.[2]
