Stefano Bontade and his brother Giovanni Bontade, who would become a lawyer, studied at a Jesuit college. In 1964, at the age of 25, Stefano Bontade became the boss of the Santa Maria di Gesù Mafia Family when his father, "Don Paolino" Bontade, stepped down because of ill-health (he suffered from diabetes). The Mafia went through difficult times at that moment. A bloody internal struggle (known as the First Mafia War) culminated in the Ciaculli Massacre in June 1963 that killed seven police and military officers sent to defuse a bomb in an abandoned Alfa Romeo Giulietta after an anonymous phone call.
