Sardinian Socialist Action Party
The party was founded in 1948 by a split from the Sardinian Action Party led by Emilio Lussu, former member of the "Sassari brigade" during the Italian resistance movement. The party won 6.6% in the first regional election in 1949 and shortly after merged with the Italian Socialist Party, a party of which Lussu was a senator until 1963.
