Foundation and early years In the July 2022 "Social Democracy" (SD), a new party in the tradition of the old PSDI, was established. In the same month the party held its first national conference during which
Umberto Costi was appointed secretary,
Dino Madaudo president and Magistro honorary president. In addition to several former activists from the PSDI, the new party was joined by
Antonio Matasso, leader of the
Sicilian Socialist Party, which became the regional secretary of the party in
Sicily. Magistro would return to the PSDI by 2023. SD, which initially wanted to contest the
2022 Italian general election as part of the centre-left, enlarged to include centrist individuals, favoured the autonomy of its regional sections and aimed to promote a new socialist constituent assembly. Finally, in the run-up of the general election, the party joined forces with
Italia Viva and
Action, aiming to represent the left wing of the
Action – Italia Viva electoral list. In the
2024 European Parliament election the party supported the
United States of Europe electoral list. During the 2025 national congress, Costi was confirmed secretary and
Antonio Esposito was elected president. ==Ideology==
