Italian Social Democratic Party

The Italian Social Democratic Party (Italian: Partito Democratico Sociale Italiano, PDSI) was an Italian social liberal political party. It dissolved in 1929.
== History ==
The Italian Social Democratic Party was formed for the 1919 general election by the union of the Constitutional Democratic Party with several other parties of the liberal left. In that occasion the PDSI, that was especially strong in Southern Italy, gained 10.9% of the vote and 60 seats in the Chamber of Deputies.
Four years later, in 1921 general election the PDSI won only 4.7% of the vote and 29 seats, partly to do with the formation of the fascist-led National Blocs and the alignment of elements of the party with that alliance.
In January 1922 the "National Council of Social Democracy and Radicalism" was officially created; this event is considered the date of the PDSI official formation and of the dissolution of the Italian Radical Party. The main party's founders were Giovanni Antonio Colonna di Cesarò, Arturo Labriola and Ettore Sacchi.
The party re-branded itself in the aftermath of the failed fascist coup d'etat known as the March on Rome, taking a staunchly anti-fascist position afterwards. It increased its vote share to 7.8% in the 1924 elections, regaining 13 seats in the process for a total of 42 seats.
The PDSI experienced a number of internal conflicts after 1924 amidst the events of the Decennio Rosso. Factionalization eventually led to the dissolution of the party shortly after the rise of the Governo Militare in 1929. Its members largely joined the Italian Reformist Socialist Party and Democratic Liberal Party, both of whom went on to support the military dictatorship.Category:Italian political parties
