Italian Reformists Socialist Party

The Italian Reformists Socialist Party [Italian: Partito Socialista Riformista Italiano, PSRI] is an Italian left Reformist party founded in Rome in 1919 after it split from the Party of Italian Workers. It is the largest party with 223 seats in the Chamber of Deputies and the current ruling party alongside the Italian Workers' Revolutionary Party. The PSRI is apart of the Coalition of Italian Workers.

History
The PSRI only officially exists since 1919, but it started as the moderate reformist branch of the Party of Italian Workers, in which it made up the majority of its members, representing those who were opposed to the more radical, Marxist branch of the party (which would later become the PRLI).

Following the assassination of Adriano Giovanardi, the Party of Italian Workers became the victim of a schism between the Reformist and Marxist branch in the party. With Giovanardi no longer present to keep the two branches together, separate parties were formed to better represent the ideology of the members. The majority founded the reformist PSRI under Vittorio Bruno. The remaining members joined the Marxist PRLI under Damiano Mancinelli.

In the Italian General Election of 1921, the PSRI managed to win a total of 223 out of 535 seats, the largest amount out of any party. This amount was, however, not enough to constitute a majority government. For this reason, a coalition was formed with the PRLI despite the differences between the members.
