The Secessionist League was a twenty-second century political union of secessionist movements in the Sol system; members of the league desired independence from the United Nations, and attempted to accomplish it through military means in 2160. While a system-wide general uprising was planned, losses in the initial rebellion caused the League to focus its resources at Jupiter, at the cost of all other operations. All efforts came to naught, however, as United Nations forces decisively defeated the League within a few months, costing the secessionist movement heavily in spacecraft, equipment, and personnel. The remnants of the Secessionist League were eventually integrated into the Friedensbewegung.
