Basil I, called the Macedonian (, Basíleios hō Makedṓn; 811 – August 29, 886) was a Byzantine Emperor who reigned from 867 to 886. Born a simple peasant in the Byzantine theme of Macedonia, he rose in the Imperial court, and usurped the Imperial throne from Emperor Michael III (r. 842–867). Despite his humble origins, he showed great ability in running the affairs of state, leading to a revival of Imperial power and a renaissance of Byzantine art. He was perceived by the Byzantines as one of their greatest emperors, and the dynasty he founded, the Macedonian , ruled over what is regarded as the most glorious and prosperous era of the Byzantine Empire.
