The Unified Socialist Party (Italian: Partito Socialista Unificato, PSU), formally the Unified PSI–PSDI (PSI–PSDI Unificati), was the name of the federation of parties formed by the Italian Socialist Party (PSI) and the Italian Democratic Socialist Party (PSDI) from 1966 to 1969. The party's membership was composed of 700,964 activists in 1966.
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 just 14.5% of the vote in the 1968 general election, due to the competition of the PSI's dissindents of the Italian Socialist Party of Proletarian Unity, the PSU returned officially to the name PSI, 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.
