Social Democratic Party (France)

The Social Democratic Party (Parti social-démocrate, PSD) was a French centrist social-democratic party.

Originally named Democratic Socialist Movement of France (Mouvement démocrate socialiste de France, MDSF), it was founded in 1973, by a split from the Socialist Party. Its founders (among them Max Lejeune, André Santini, Pierre-Cristophe Baguet, Charles Baur, Émile Muller, Joseph Klifa and Auguste Locoeur) opposed to the alliance with the French Communist Party arranged by François Mitterrand on behalf of the Socialist Party based on the Common Programme.

In 1978, it joined the Union for French Democracy, the center-right confederation created in order to support President Valéry Giscard d'Estaing. In 1995, it merged with the Centre of Social Democrats, the Christian-democratic component of the confederation, to form Democratic Force.
