Salvatore Maranzano
After the Gennas fled, the Aiello brothers declared themselves the bosses of the old Genna territory. The Aiellos had an alliance with Castellammarese Clan boss Salvatore Maranzano and a close connection to the North Siders. They attempted to murder Capone to become the most powerful Italian organization in Chicago. In 1930, Joe Aiello was murdered and Capone took over the territory.
