The ProgSoc Movement is a Sector wide social movement that advocates a progressive version of socialism that is based on radical democracy, social libertarianism, pacifism and a nationalisation of key industries. At the same time, ProgSoc argues for maintaining a highly fragmented and competitive free market in areas that are unlikely to be subject to oligopolisation.

The Movement has largely been a concentration of people with similar ideas, and as is often want to happen in such situations there have been political organisations created using the ProgSoc Movement and its ideals as a base, one of the more famous is the ProgSoc Faction of the Anax One parliament headed by Eileen Xiaobo.
