Born in a humble family in
Catania, he spent his childhood years in a children’s home. His father had been killed in 1868 by the Carabinieri during a robbery, while his mother, according to a report by the authorities, "lived in immorality." Released from the home, he found employment as an archivist clerk in the prefecture in 1878. His combative temperament was played out in journalism. A little over twenty years, in 1880, he founded the political weekly
Lo staffile (The Whip), whose very title reflected the polemic nature of its contents. Due to his continuous attacks against local authorities, he soon had to leave his job at the prefecture. To feed the family and attend school, he practised many trades: wine seller, salesman of sewing machines, a printer, and even playing the
tuba in a band. He graduated in Law, passed the examinations of an attorney, but did not practice the legal profession ever. A few years later, he was involved with the weekly ''L'unione'' (The Union), which had emerged as the organ of the Republican Club, and became the workers' organ of Catania. De Felice was very active in organizing workers. In 1890, he convened the first congress of workers' associations in Sicily, with the adhesion of a couple of hundred associations. However, the congress was prohibited by the police superintendent of Catania, on the orders of Prime Minister
Francesco Crispi. He married at the age of seventeen and had four daughters in a few years. But his turbulent life led his wife, Giuseppa De Simone, to break off the relationship. After the break-up, De Felice would have a busy, but rather inordinate, love life. ==Fasci Siciliani==
