Socialist Workers' Party of Germany
The Socialist Workers' Party of Germany (, SAPD) was a centrist Marxist political party in Germany. It was formed as a left-wing party with around 20,000 members which split off from the SPD in the autumn of 1931. In 1931, the remnants of Independent Social Democratic Party of Germany (USPD) merged into the party and in 1932 some Communist Party dissenters also joined the group as well as a part from the Communist Party Opposition. Nevertheless, its membership remained small. From 1933, the group's members worked illegally against Nazism.
