Eastern Roman Empire (Byzantine Empire) / Λέων ΣΤ΄ ὁ Σοφός (Emperor Leo VI)

Leo VI, called the Wise or the Philosopher (Greek: Λέων ΣΤ΄ ὁ Σοφός), was Byzantine Emperor from 886 to 912. The second ruler of the Macedonian dynasty (although his parentage is unclear), he was very well-read, leading to his surname. During his reign, the renaissance of letters, begun by his predecessor Basil I, continued; but the Empire also saw several military defeats in the Balkans against Bulgaria and against the Arabs in Sicily and the Aegean.
