One of Luciano’s defining moments was his involvement in the Castellammarese War, a bloody power struggle among Italian-American mafiosi. After orchestrating the assassination of Salvatore Maranzano, the last self-declared "boss of bosses," Luciano abolished the position altogether and established The Commission in 1931. The Commission was a governing body designed to mediate disputes and oversee the activities of various crime families, solidifying Luciano’s position as the architect of modern organized crime. He also founded what is known today as the Genovese crime family, which remains one of the most powerful Mafia families in the U.S.
