Nikephoros I, also known as Nicephorus I, was the Byzantine emperor from 802 to 811. He began his career as genikos logothetēs under Empress Irene, but later overthrew her to seize the throne. Prior to becoming emperor, he was sometimes referred to as "the Logothete" and "Genikos" or "Genicus", in recognition of his previous role.
Michael I Rangabé was Byzantine emperor from 811 to 813.
Staurakios, also called Stauracius, was Byzantine emperor from 26 or 28 July to 2 October 811. He was born in the early 790s, probably between 791 and 793, to Nikephoros I and an unknown woman. Nikephoros seized the throne of the Byzantine Empire from Empress Irene in 802, and elevated Staurakios to co-emperor on 25 December 803. On 20 December 807, a bride show was held by Nikephoros to select a wife for Staurakios, which resulted in his marriage to Theophano of Athens, a kinswoman of Irene. Little else is known of him until he came to take the throne upon the death of Nikephoros.
Krum, often referred to as Krum the Fearsome was the Khan of Bulgaria 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 Dnieper 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.
The Battle of Pliska or Battle of Vărbitsa Pass was a series of battles between troops, gathered from all parts of the Byzantine Empire, led by the Emperor Nicephorus I, and the First Bulgarian Empire, governed by Khan Krum. The Byzantines plundered and burned the Bulgar capital Pliska which gave time for the Bulgarians to block passes in the Balkan Mountains that served as exits out of Bulgaria. The final battle took place on 26 July 811, in some of the passes in the eastern part of the Balkans, most probably the Vărbitsa Pass. There, the Bulgarians used the tactics of ambush and surprise night attacks to effectively trap and immobilize the Byzantine army, thus annihilating almost the whole army, including the Emperor. After the battle, Krum encased the skull of Nicephorus in silver, and used it as a cup for drinking. This is one of the most documented instances of the custom of the skull cup.
Pliska was the first capital of the First Bulgarian Empire during the Middle Ages and is now a small town in Shumen Province, on the Ludogorie plateau of the Danubian Plain, 20 km northeast of the provincial capital, Shumen.
