Frieden

In 2160, before the formation of the UEG and UNSC, the Frieden, a resurgent Neo-Nazi/National Socialist movement springing from anti-Koslovic sentiment in the Jovian Moons (largely backed by Unified German Republic corporations, frequent targets of Koslovic "workers' crusades") was formed to achieve peace by destroying the "oppressors on Terra Firma" and it attacked the UN Colonial Advisors on Io, sparking the Jovian Moons Campaign, the Rain Forest Wars, a series of clashes on Mars, and the Interplanetary War. Both the Frieden and the Koslovics were defeated. "Frieden" literally means "peace"—in this case, they believed that peace could be achieved only once the "oppressors on Terra Firma" were eliminated.

Organizational Aims
Judging by the term "secessionist", it is clarified that the Frieden movement's main goal was to separate itself from the United Nations' authority and create an independent government in the Jovian Moons.
