The Byzantine Empire under the Nikephorian dynasty began following the deposition of the Byzantine empress Irene of Athens, the throne of the Byzantine Empire passed to a relatively short-lived dynasty, the Nikephorian dynasty, named after its founder, Nikephoros I. The empire was in a weaker and more precarious position than it had been for a long time and its finances were problematic.^[1]

During this era Byzantium was almost continually at war on two frontiers which drained its resources, and like many of his predecessors, Nikephoros (802–811) himself died while campaigning against the Bulgars to the north. Furthermore, Byzantium's influence continued to wane in the west with the crowning of Charlemagne (800–814) as Holy Roman emperor by Pope Leo III at Old St. Peter's Basilica in Rome in the year 800 and the establishment of a new empire in Western Europe laying claim to the universal Roman monarchy.
