§ Where Pietro Nenni stands
3 axesNenni sought public ownership and planning within a democratic republic. The nationalisation of electricity in 1962, which created ENEL, was a Socialist condition for backing the centre-left, and his party pushed national economic programming, embodied in the 1966–70 national economic plan prepared by Socialist budget ministers.
Nenni was an anti-fascist who worked through parliament, but for two decades his socialism leaned toward the Communists: the 1934 unity-of-action pact and the 1948 Popular Democratic Front tied the Socialists to Palmiro Togliatti's party. Only after 1956 did he steer them toward government with the Christian Democrats, accepting the constitutional state as the frame for reform.
Nenni was a progressive republican and internationalist. He campaigned for the republic in the 1946 referendum that ended the monarchy, and the centre-left era he opened produced social reforms such as the 1970 law legalising divorce, sponsored by the Socialist deputy Loris Fortuna and upheld by voters in a 1974 referendum.

§ The story
HistoricalPietro Nenni (1891–1980) was the dominant figure of Italian socialism for half a century. Born in Faenza and raised partly in an orphanage, he began as a republican agitator, shared a prison cell with Benito Mussolini in 1911 after protests against the war in Libya, and joined the Italian Socialist Party in 1921, soon editing its newspaper Avanti!. Driven into exile in France in 1926, he led the party abroad, went to Spain to support the Republic in its civil war and was later confined by the Fascists on the island of Ponza.
After the war Nenni was deputy prime minister and, in 1946–47, foreign minister, and he campaigned hard for the republic in the 1946 referendum. His long alliance with the Communists split the party in 1947 and ended in defeat in the 1948 election, but after the Soviet crushing of Hungary in 1956 he broke with them and in 1963 led the Socialists into Aldo Moro's first centre-left government as deputy prime minister. His daughter Vittoria died in Auschwitz in 1943. He became a life senator in 1970.

Was Pietro Nenni left-wing or right-wing?
Left-wing. Nenni led the Italian Socialist Party for most of the period from the 1930s to the 1960s, fought Fascism from exile and allied with the Communists into the 1950s.
