History

The two parties joined forces in 1966, after the PSI had joined the Italian government in 1963 for the first time since 1947, as part of Aldo Moro's cabinets, composed of Christian Democracy, the Italian Republican Party, and the PSDI. The united party achieved 14.5% of the vote in the 1968 Italian general election,^[4] and suffered losses due to the competition of the PSI's dissidents of the Italian Socialist Party of Proletarian Unity. The PSI–PSDI returned officially to the name PSI in October 1968, causing the split of the PSDI's former members in July 1969; these formed the United Socialist Party, which was finally renamed PSDI in 1971.^[2]
