Overview
The Macedonian dynasty (Greek: Μακεδονική Δυναστεία) ruled the Byzantine Empire from 867 to 1056, following the Amorian dynasty. During this period, the Byzantine state reached its greatest extent since the Early Muslim conquests, and the Macedonian Renaissance in letters and arts began. The dynasty was named after its founder, Basil I the Macedonian who came from the theme of Macedonia.
Origins
The dynasty's ethnic origin is unknown, and has been a subject of debate. During Basil's reign, an elaborate genealogy was produced that purported that his ancestors were not mere peasants, as everyone believed, but descendants of the Arsacid (Arshakuni) kings of Armenia, Alexander the Great and also of Constantine the Great. Some Persian writers such as Hamza al-Isfahani or Al-Tabari, called Basil a Saqlabi, an ethnogeographic term that usually denoted the Slavs, but it can be interpreted as a generic term encompassing the inhabitants of the region between Constantinople and Bulgaria.
Thus, claims have been made for the dynasty's founder (Basil I) being of Armenian, Slavonic, or "Armeno-Slavonic" descent from his paternal side.
