The Socialist Party (Parti Socialiste or PS) is the main opposition party in France. Although it has historically been a democratic socialist party, and still defines itself as such, most political scientists would say that it is now a social democratic party. It was founded in 1969. A democratic socialist party has existed in France under various names since 1880. For a century, however, it had only fleeting electoral success. In 1981, under François Mitterrand, party won both the presidency and (with allies) a majority in the National Assembly for the first time, and was president for 14 years.
