Rally of Republican Lefts in the context of Independent Radicals

The Democratic Alliance (French: Alliance démocratique, AD), originally called Democratic Republican Alliance (Alliance républicaine démocratique, ARD), was a French political party created in 1901 by followers of Léon Gambetta such as Raymond Poincaré, who would be president of the Council in the 1920s. The party was originally formed as a centre-left gathering of moderate liberals, independent Radicals who rejected the new left-leaning Radical-Socialist Party, and Moderate Republicans (Gambetta and the like), situated at the political centre and to the right of the newly formed Radical-Socialist Party. However, after World War I and the parliamentary disappearance of monarchists and Bonapartists it quickly became the main centre-right party of the Third Republic. It was part of the National Bloc right-wing coalition which won the elections after the end of the war. The ARD successively took the name "Democratic Republican Party" (Parti Républicain Démocratique, PRD), and then "Social and Republican Democratic Party" (Parti Républicain Démocratique et Social), before becoming again the AD.

The ARD was largely discredited after supporting the Vichy regime during World War II, an option strongly supported by its major leader Pierre-Étienne Flandin and other members such as Joseph Barthélemy. The centre-right party tried to reform itself under the direction of Joseph Laniel, who had taken part in the Resistance. It temporarily joined the Rally of Republican Lefts (Rassemblement des gauches républicaines, RGR) before merging into the National Center of Independents and Peasants (Centre national des indépendants et paysans, CNIP). The AD, which in contrast to the French Section of the Workers' International (SFIO) or the French Communist Party (PCF), never became a mass political party founded on voting discipline (in these left-wing parties deputies usually vote in agreement with the party's consensus), turned at that time in little more than an intellectual circle whose members met during suppers. However, it was dissolved in only 1978, long after its effective disappearance from the political scene.
