Basil I

Basil I, nicknamed "the Macedonian" (Greek: Βασίλειος ὁ Μακεδών, translit. Basíleios ō Makedṓn; 811 – 29 August 886), was Byzantine emperor from 867 to 886. Born a lowly peasant in the theme of Macedonia, he rose to prominence in the imperial court after entering into the service of Theophilitzes, a relative of Emperor Michael III (r. 842–867). He was given a fortune by the wealthy Danielis and gained Michael's favour, whose mistress he married on his emperor's orders. In 866, Michael proclaimed him co-emperor, but Basil ordered his assassination the next year, thus installing himself as sole ruler of the empire. Despite his humble origins, he showed great ability in running the affairs of state, and founded the Macedonian dynasty. He was succeeded upon his death by his son (perhaps actually Michael III's son) Leo VI.
