The Italian Radical Party was a radical political party in Italy that was founded in 1904 as the successor of the Historical Far Left grouping. Associated with radicalism, republicanism, secularism, social liberalism, and anti-clericalism, the party was strongest in Lombardy, northern Veneto and Friuli, Emilia-Romagna, central Italy, and the outskirts of Rome. The party later lost votes to the PSI in Emilia and to the Italian Republican Party in Romagna, but the party strengthened its position in Veneto and in southern Italy, where they were previously virtually nonexistent. The party won 10.4% of the vote and 62 seats in the Chamber of Deputies in 1913, and the party shifted towards the center after allying with Giovanni Giolitti's Liberal Union. In 1921, the party joined forces with several minor liberal parties to form the Democratic Liberal Party, doing well in Piedmont and the south and winning 15.9% of the vote. In 1922, the party merged into the Italian Social Democracy Party (PDSI).
