Byzantine emperor Nikephoros I plunders the Bulgarian capital of Pliska and captures Khan Krum's treasury.
Byzantine Empire
The Byzantine Empire, also known as the Eastern Roman Empire, was the continuation of the Roman Empire centred on Constantinople during late antiquity and the Middle Ages. Having survived the events that caused the fall of the Western Roman Empire in the 5th century AD, it endured until the fall of Constantinople to the Ottoman Empire in 1453. The term 'Byzantine Empire' was coined only after its demise; its citizens used the term 'Roman Empire' and called themselves 'Romans'.
Nikephoros I
Nikephoros I, also known as Nicephorus I, was Byzantine emperor from 802 to 811. He was General Logothete under Empress Irene, but later overthrew her to seize the throne for himself. Prior to becoming emperor, he was sometimes referred to as "the Logothete" and "Genikos" or "Genicus", in recognition of his previous role as General Logothete.
First Bulgarian Empire
The First Bulgarian Empire was a medieval state that existed in Southeastern Europe between the 7th and 11th centuries AD. It was founded in 680–681 after part of the Bulgars, led by Asparuh, moved south to the northeastern Balkans. There they secured Byzantine recognition of their right to settle south of the Danube by defeating – possibly with the help of local South Slavic tribes – the Byzantine army led by Constantine IV. During the 9th and 10th century, Bulgaria at the height of its power spread from the Danube Bend to the Black Sea and from the Dnieper River to the Adriatic Sea and became an important power in the region competing with the Byzantine Empire.
Pliska
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.
