The Popular Democratic Party (, PDP) was a Christian democratic political party in France during the Third Republic. Founded in 1924, it represented the trend of French social Catholicism, while remaining a party embodying the ideology of centrism. The party's ideology was inspired by the popularism of Luigi Sturzo's Italian People's Party. The PDP was a co-founder in 1925 of the International Secretariat of Democratic Parties of Christian Inspiration (SIPDIC). The PDP had its roots in French Catholicism and various Christian movements inspired by Hugues Felicité Robert de Lamennais and later continued by Marc Sangnier's Le Sillon, the Young Republic League and the Popular Liberal Action (ALP), the party of republican Catholics founded in 1902 and dissolved in 1919. History Foundation The creation of the PDP has its premises in the context of the immediate post-war, the reintegration of Catholics in the nation by the wartime Union sacrée and the involvement of Catholics in power during the National Bloc (1919–1924). From the National Bloc, fourteen deputies founded the core of the PDP prior to the 1924 legislative election. Established by Congress on 15 and 16 November 1924, under the chairmanship of George Thibout and involving 200 delegates, the PDP supported the desire to achieve "a task in bringing reconciliation around the idea of Republicanism" by the definition of "new Republican faith" The Popular Democrats advocated that religion was not and should not be a line between right and left. However, the PDP oriented itself to the centre-right in direct competition to the Republican Federation, the party from which most of the PDP's members came from and where social Catholics concentrated since the demise of the ALP. 19321940 Faced to the governing left-wing Cartel des Gauches, the PDP ranked itself in the parliamentary opposition but stayed outside of the National Catholic Federation (FNC), founded by General Édouard de Castelnau as a reaction to the perceived anti-clerical legislation passed by Édouard Herriot's cabinet. The PDP supported the ministries of Raymond Poincaré, seduced by his stabilizing of the economic situation, but hostile to the lack of social legislation. In addition, the PDP developed the popular theme of "party of the centre" or "Cartel of the Centres", which explained their support for the Ministry led André Tardieu (November 1929-February 1930). Despite its position, the PDP had little weight in the different governments formed between 1926 and 1932. Only Auguste Champetier de Ribes participated in
