Which Byzantine dynasty began with Basil I in 867?

The Macedonian dynasty began with Basil I, who became Byzantine emperor in 867. Basil seized the throne after arranging the assassination of Emperor Michael III, whose co-emperor he had become the previous year.

The dynasty is named after the Byzantine theme of Macedonia, where Basil was traditionally said to have been born or raised, although historians have debated his family’s ethnic background. Basil’s rise was remarkable: he came from comparatively humble origins, entered imperial service, gained Michael III’s favor, and eventually transformed that access into supreme power.

The Macedonian dynasty ruled from 867 to 1056 and presided over one of Byzantium’s strongest periods. Its emperors expanded or stabilized the empire, promoted military successes, supported cultural learning, and helped produce the Macedonian Renaissance. The name can cause confusion because Basil I was nicknamed “the Macedonian,” but the dynasty refers to the ruling house he founded, not simply to every emperor’s birthplace. Later rulers included Leo VI, Constantine VII, and Basil II.
