Le Siècle is an elite bi-partisan social club in France that meets once a month for dinner at the French Automobile Club in Paris's Place de la Concorde. Membership in Le Siècle "symbolizes the French nomenklatura" and includes France's top intellectuals, politicians, chief executives, journalists, and artists; since the 1970s, one-third to half of all French government ministers were members of Le Siècle, regardless of political affiliation or party membership. That percentage peaked at 72% under Prime Minister Édouard Balladur (1993–95). French journalist and writer Emmanuel Ratier wrote in 1996 that the club's membership controls 90% of French GDP. 
There are 580 members, subject to change every year, and 160 guests.
Le Siècle (English: 'the Century') was founded in 1944 by Georges Bérard-Quélin, a journalist and Freemason. The small group of the 1940s and 1950s eventually expanded to include major politicians across the political spectrum, from François Mitterrand, who was close associate of Bérard-Quélin, to Georges Pompidou via Pierre Mendès France. When a similar think tank called the Saint-Simon Foundation dissolved in 1999, many of its former members joined Le Siècle.
In the immediate post-war period, deep cleavages fragment the ruling class: resistance fighters against Vichy collaborators; bosses - liberal or right-wing - against senior planning officials; disunited political parties against a Communist Party at the height of its electoral results. Bérard-Quélin and his associates worked to reconcile the elites, and to exclude the communists.
"I really like Le Siècle," says Mrs. Martine Aubry. I stopped going there in 1997 when I became minister. It was very interesting. I found myself at tables with extremely different people (...). The initiative can be perceived as totally elitist, but it remains a real meeting place. I learned a lot from it. Because, for me, real intelligence means trying to understand people who have a different logic." The former right-hand man of Mr. Jacques Delors, Mr. Pascal Lamy, current director general of the World Trade Organization (WTO), explains his presence as a form of getting access: "It is important that the men on the left don't let the decision-makers be in contact only with the right." Others, like Pierre Moscovici, admit straight away that Le Siècle turns out to be" a very influential social network."
