In Roman mythology, King Numitor (Classical Latin: [ˈnʊmɪtɔr]) of Alba Longa was the maternal grandfather of Rome's founder and first king, Romulus, and his twin brother Remus. He was the son of Procas, descendant of Aeneas the Trojan, and father of the twins' mother, Rhea Silvia, and Lausus.
In 794 BC Procas died and was meant to be succeeded by Numitor. Instead he was overthrown and removed from the kingdom by his brother, Amulius, who had no respect for his father's will or his brother's seniority. Amulius also murdered Numitor's sons, in an effort to remove power from his brother for himself.
