814 deaths

Charlemagne ( ; 2 April 748 – 28 January 814) was King of the Franks from 768, King of the Lombards from 774, and Emperor of what is now known as the Carolingian Empire from 800. He united most of Western and Central Europe and was the first recognised emperor to rule from the west after the fall of the Western Roman Empire approximately three centuries earlier. Charlemagne's reign was marked by political and social changes that had lasting influence on Europe throughout the Middle Ages.

Krum (, ), often referred to as Krum the Fearsome (c. mid 8th century – 13 April 814) was the Khan of First Bulgarian Empire from sometime between 796 and 803 until his death in 814. During his reign the Bulgarian territory doubled in size, spreading from the middle Danube to the Dniester and from Odrin to the Tatra Mountains. His able and energetic rule brought law and order to Bulgaria and developed the rudiments of state organization.

Angilbert, Count of Ponthieu ( – 18 February 814) was a noble Frankish poet who was educated under Alcuin and served Charlemagne as a secretary, diplomat, and son-in-law. He is venerated as a pre-Congregation saint and is still honored on the day of his death, 18 February.

Reginfrid (or Ragnfrid) (died 814) was a co-King of Denmark from 812, when Hemming I died, to 813, when he and his brothers were ousted by the sons of a previous king, Gudfred. He was probably a son of Halfdan, a Danish leader who became a vassal of Charlemagne in 807, and brother of Anulo (died 812), Hemming (died 837), and Harald Klak (died c. 852). He was probably also related to the Danish king he succeeded.

Frodoald (died in 814) was the Count of Vannes from 799 to around 814.

Dukum () was probably a brother of the Bulgarian khan Krum (r. 803–814), who might have succeeded Krum as the ruler of Bulgaria for a few weeks or months. After him, the throne was taken by Ditzeng, who died shortly under unclear circumstances. At the end of 814 or early 815 Krum's son Omurtag ascended the throne, thus ending the succession crisis. The circumstances of Dukum's death are unknown and hypothesis can be ruled out, including a possible involvement of Omurtag himself.
