Byzantine Empire /
(813-842) Byzantine emperor 829-842.
Theophilus appears both to have been an active and just leader, good at running the finances of the empire and improving the administration in the empire. Still, he was also very brutal on many occasions. Among the first things he did as emperor was to execute his father's allies from the coup that made him emperor.
He was the last Iconoclastic emperor, and was in the beginning quite brutal in his suppression of icon worshipping. Gradually, he came to realize that too many favoured icon worship to realistically expect its final demise.
On the international arena, he was forced to fight the Muslims, both in Sicily and in Anatolia. In the north, Vikings and Magyars were the main challenges, motiving the construction of an extensive line of fortresses.
Theophilus was very much inspired by the example of Abbasid Caliph Harun ar-Rashid, and he reportedly made many walks around the capital disguising his position as emperor, listening to the thoughts of his subjects.
Theophilus had the University of Constantinople restored. He gave much attention to learning in general.
