Radical Party (France)

The Radical Party (French: Parti radical), officially the Republican, Radical and Radical-Socialist Party (French: Parti républicain, radical et radical-socialiste), is a liberal and social-liberal political party in France. Since 1971, to prevent confusion with the Radical Party of the Left (PRG), it has also been referred to as Parti radical valoisien, after its headquarters on the rue de Valois. The party's name has been variously abbreviated to PRRRS, Rad, PR and PRV. Founded in 1901, the PR is the oldest active political party in France.

Coming from the Radical Republican tradition, the PR upheld the principles of private property, social justice and secularism. The Radicals were originally a left-wing group, but, starting with the emergence of the French Section of the Workers' International (SFIO) in 1905, they shifted gradually towards the political centre. In 1926, its right-wing split off to form the Unionist (or National) Radicals. In 1971 the party's left-wing split off to form the PRG. The PR then affiliated with the centre-right, becoming one of the founder parties of the Union for French Democracy (UDF) in 1978. In 2002, the party split from the UDF and became an associate party of the Union for a Popular Movement (UMP) and were represented on the Liaison Committee for the Presidential Majority prior to launching The Alliance (ARES) in 2011 and the Union of Democrats and Independents (UDI) in 2012. After the 2017 presidential and legislative elections, negotiations to merge the PR and the PRG began. The refounding congress to reunite the parties into the Radical Movement was held in December 2017. However, the union proved short-lived and, by 2021, both the PR and PRG returned to be independent parties. The PR was then part of the Ensemble Citoyens coalition.
