Basil I

Basil I, nicknamed "the Macedonian", was Byzantine emperor from 867 to 886. Born to a peasant family in the theme of Macedonia, he rose to prominence in the imperial court after gaining the favour of Emperor Michael III, whose mistress he married on his emperor's orders. In 866, Michael proclaimed him co-emperor. Fearing a loss of influence, Basil orchestrated Michael's assassination the next year and installed himself as sole ruler of the empire. He was the first ruler of the Macedonian dynasty.
