The China Democratic Socialist Party (CDSP; Chinese: 中國民主社會黨; pinyin: Zhōngguó shèhuì mínzhǔdǎng) was founded in Shanghai on 15 August 1946. It was formed through the merger of the former Chinese National Socialist Party (Chinese: 中國國家社會黨; their preferred shorthand name was "Socialists" and had no relation to the German Nazi party) and the Democratic Constitutionalist Party (Chinese: 民主憲政黨), both of which had survived the years of Japanese aggression by generally supporting the Kuomintang-led national government. The new party's first head was Dr Carsun Chang (Zhang Junmai).
