The House of Monomachos, Latinized Monomachus (Greek: Μονομάχος, lit. 'Lone Warrior'), feminine form Monomachina (Μονομαχίνα), was the name of a Byzantine aristocratic family active in the 10th–15th centuries and possibly even before that. The name, Monomachos, means “the gladiator” in Greek.[1] It produced several officials and military commanders, as well as one emperor, Constantine IX Monomachos (r. 1042–1055).
