In October 1939, an underground group of mainly journalists, writers and artists was founded as the Socialist Organisation "Freedom".
As early as November 1939, the group drafted its first programme document, the Ideological Manifesto, in which, opposing the aggression of Germany and the USSR, it was stated that "the main aim of the struggle of the Polish working masses is the restoration of full political independence and sovereignty of Poland, and the consolidation of its existence based on the principles of democracy and social justice".

The chairman of the Main Committee, Zbigniew Mitzner, sought to subordinate the organisation to the PPS-WRN, and was particularly close to Zygmunt Zaremba.
