History
Social Democratic Party (Sozialdemokratische Partei Deutschlands)
The history of Weimar is largely the history of the Social Democrats: their successes and their failures. They were the ones who chose the character of the new regime: state continuity and parliamentary compromises or the Soviet left-radical alternative? The first leaders of the republic were Social Democrats, and the SPD remained the most popular party in the country until the summer of 1932. Ultimately, the crisis of the Social Democrats and their paralysis of will in the struggle for the republic became harbingers of its final collapse.
