The 'Democratic and Socialist Union of the Resistance' (''Union démocratique et socialiste de la Résistance'' or UDSR) was a French right-of-center political party found at the Liberation and in activity during the
Fourth Republic (1947-58). It was a founding member of the
Liberal International in 1947.
Foundation
It was founded in 1945 by the non-Communist
resistance network
Movement of National Liberation. The project was to create a French labour party with all the former non-Communist
Resistance. However, this plan failed because of the rebirth of the Socialist
SFIO and the emergence of the new Christian-Democratic party
Popular Republican Movement (MRP) and then of the
Gaullist party (
RPF). Henceforth, the UDSR associated itself with the
Radical Party, who had been in government during most of the
Third Republic, in the
Rally of the Republican Lefts (''Rassemblement des gauches républicaines'' or RGR), which presented itself as an alternative to the ''
tripartisme'' alliance between the SFIO, the MRP and the
French Communist Party (PCF). Its name is a typical example of French ''
sinistrisme'', whereas politicians tended to reject right-wing terms, prefering to label themselves as left-wing.
Fourth Republic
Following the
May 1947 crisis during which
Maurice Thorez, Communist vice-premier, and four others PCF ministers left
Paul Ramadier's government, the UDSR took part in the
Third Force which gathered radicals and others conservative politicians. It remained through-out the Fourth Republic a minor centerist political party which participated to the governments. Its president
René Pleven was named president of the Council from 1951 to 1952, before being succeeded by
Antoine Pinay (
CNIP). But Pleven's leadership was eventually challenged by
François Mitterrand who advocated a realignment to the Left, and took the lead in 1953.
In 1956, the UDSR participated to the center-left coalition
Republican Front, headed by
Pierre Mendès-France, which won the legislative election. However, two years later, the UDSR imploded. Indeed, Pleven and the conservative wing approved
Charles de Gaulle's come back during the
May 1958 crisis, in the midst of the
Algerian War and threats of a coup d'état, and the institutions of the
Fifth Republic, contrary to Mitterrand who called the new Constitution a "permanent coup d'état."
Legacy
The UDSR survived until 1964, when it merged in Mitterrand's
Convention des institutions républicaines (CIR), which itself merged at the 1971
Epinay Congress in the new
Socialist Party (PS), which is currently the main left-wing party in France.
