The Korean Social Democratic Party (KSDP) is a political party in North Korea that is allied with the ruling Workers' Party of Korea (WPK). It was formed on 3 November 1945 as the Korean Democratic Party by a mixed group of entrepreneurs, merchants, handicraftsmen, petite bourgeoisie, peasants, and Christians. The party's founders were motivated by anti-imperialist and anti-feudal aspirations, and aimed to eliminate the legacy of Japanese rule and build a new democratic society. The party came under greater influence of the ruling government over time, and today is under the effective control of the WPK.
