Issy-les-Moulineaux Congress
The Issy-les-Moulineaux Congress was the second national congress of the French Socialist Party. It took place on 11 to 13 July 1969. This marked the transformation of the old French Section of the Workers' International into the new PS. However, François Mitterrand's Convention of Republican Institutions did not attend.
Jean Poperen, expelled from the Unified Socialist Party, joined the PS.
