Liberalism and radicalism have played a role in the political history of Italy since the country's unification, started in 1861 and largely completed in 1871, and currently influence several leading political parties. During the first decades of Italy as a united country, the main parliamentary parties included liberals, but it was not until 1877 that the left-wing Radical Party was established as the first organized liberal party. The more centrist Liberal Union followed in 1913. Most liberal and radical parties were banned in 1926 under Benito Mussolini's Fascist government.
