The history of the Italian Republic concerns the events relating to the history of Italy that have occurred since 1946, when Italy became a republic after the 1946 Italian institutional referendum. The Italian republican history is generally divided into two phases, the First and Second Republic.
After the fall of the Fascist regime in Italy and the end of World War II, Italian politics and society were dominated by Christian Democracy (DC), a broad-based Christian political party, from 1946 to 1994. From the late 1940s until 1991, the opposition was led by the Italian Communist Party (PCI). Christian Democracy governed uninterrupted during this period, dominating every cabinet and providing nearly every prime minister. It governed primarily with the support of an array of minor parties from the centre-left to the centre-right, including the Italian Socialist Party (PSI), Italian Democratic Socialist Party (PSDI), Italian Republican Party (PRI), and Italian Liberal Party (PLI), and even far-right parties like the Italian Social Movement (MSI). The Communist Party was excluded entirely from government, with the partial exception of the short-lived Historic Compromise, in which the PCI provided external support to a DC minority government from 1976 to 1979.
