in
New York City, October 1946 In 1944, Di Vittorio, along with socialist and Catholic union leaders, agreed to re-establish CGIL as a representative of all currents of trade unionism in Italy, including communists,
socialists,
Christian democrats, and
anarcho-syndicalists. He was elected union secretary the following year. As a union representative, Di Vittorio sat on the
National Council, an advisory body created to fulfill the role of a provisional legislature from September 1945 to June 1946. In the
1946 Italian general election, he was elected to the
Constituent Assembly as a member of the
Italian Communist Party (PCI), and would later be re-elected as a member of the new Parliament in the
1948 and
1957 Italian general elections. With the onset of the
Cold War and the breakdown of the alliance between the main anti-fascist parties, particularly
Christian Democracy (DC) and the Italian Communist Party, the organisation suffered internal divisions. When a right-wing student attempted to assassinate the PCI leader
Palmiro Togliatti in July 1948, CGIL called a general strike and organised street protests during which widespread rioting occurred. After this event, those affiliated with the Christian Democrats within the union left to establish the
Confederazione Italiana Sindacati Lavoratori (CISL). They were followed in May 1949 by supporters of the
Italian Democratic Socialist Party, which split from the PSI and left to form what would become the
Unione Italiana del Lavoro (UIL). These three organisations continue to be Italy's main labour unions. During the
Hungarian Revolution of 1956, Di Vittorio clashed with Togliatti over the CGIL's statements of support for the Hungarian insurgents. According to
Antonio Giolitti, this position was supported by Di Vittorio himself during private meetings, and archival documents show that the CGIL secretary faced pressure from the PCI leadership to retract the statements. Di Vittorio continued leading CGIL as Italy's largest union with the backing of the PCI and PSI until his death from
heart attack in 1957. He was also a longtime leader of the
World Federation of Trade Unions. His strong charisma made him the most popular myth of the Italian workers. His funeral was attended by more than three million people coming to Rome from all over Italy. ==Electoral history==
