Events

= By place =

== Byzantine Empire ==

  • Byzantine–Bulgarian War: Emperor Nikephoros I organises a new campaign against the Bulgarian Empire, gathering an expeditionary force (most of the Roman army) from all parts of the empire. He is accompanied by high-ranking officials and aristocrats, including his son Stauracius and brother-in-law Michael I RangabeAnonymus Vaticanus, p. 148. (both later emperors temporarily). Krum, ruler (khan) of Bulgaria, sends envoys to sue for peace. Nikephoros refuses to accept the terms and marches through the Balkan passes towards Pliska, the Bulgarian capital.
  • July 23 – Nikephoros I reaches Pliska, and destroys a Bulgarian army of 12,000 elite soldiers who guard the stronghold. Another hastily assembled relief force of 50,000 soldiers suffers a similar fate.Anonymus Vaticanus, pp. 148-149. The Byzantines capture the defenseless capital. Nikephoros plunders the city and captures Krum's treasury.Anastasius Bibliothecarius. Chronographia tripertita, p. 329. He burns the countryside, slaughters sheep and pigs, as he pursues the retreating Bulgars southwest towards Serdica (modern-day Sofia).Anonymus Vaticanus, p. 150.
  • July 26 – Battle of Vărbitsa Pass: Nikephoros I is trapped (probably in the Vărbitsa Pass) and defeated by the Bulgars, who use the tactics of ambush and surprise night attacks to immobilize the Byzantine forces. Nikephoros himself is killed; Krum has the emperor's head carried back in triumph on a pole, where it is cleaned out, lined with silver and made into a jeweled skull cup, which he allows his Slavic princes (archons) to drink from with him.{{The Early Medieval Balkans|p=97}}
  • Stauracius is installed as emperor at Adrianople (the first time a Byzantine emperor is crowned outside Constantinople). Because of a sword wound near his neck (during the Battle of Pliska), Stauracius is paralyzed. The imperial court is split between the noble factions of his wife Theophano and his sister Prokopia.{{A History of the Byzantine State and Society|page=429}}
  • October 2 – Michael I is declared emperor of the Byzantine Empire; Stauracius is forced by senior officials to retire to a monastery.{{A History of the Byzantine State and Society|page=429}}
