The Social Justice Party is one of the three major parties of the New Helvetia Confederation, along with the Classical Party and the Nationalist Helvetian Party. The Social Justice Party traces back to the Republican Party and some social liberals of the Democratic Party. Since the Helvetian Valley Revolution the Social Justice Party supported progressive reform, protesting against segregation, and going against the social conservative policies of the Nationalist Party.
Holding the majority in the Sacramento Valley, most are Roman Catholic and identify with with Swiss-American. While holding partial control of the assembly seats in the Canton of New Berne Bay the party cannot challenge the Nationalists at the cantonal level due to the area being more concerned on issues of economics. Holding a Laissez-faire economic policy since 1977, the party lost a major coalition to the Nationalists when many of economic liberals saw that the party was out of touch with low income and middle income families.
In 1966, with the signing of the Federal Charter of 1966 the two main dominating positions were unified within the nation, both the followers of Johnathan Williams and Zachary Birnen followed under the same banner, that of the Social Justice Party. In respect to the south, northern party members respected the social policies, because Birnen had demanded the party stay together on terms that if a division came in the Helvetian Assembly no progress would occur. In 1969 when the Assembly voted on the Palacade Admission Act gave way for Williams to rally his own party in the defense of segregation. 35 members left the Social Justice Party and gave way to a long decline of the party.
