Socialist Unity Party of Germany

The Socialist Unity Party of Germany (German: Sozialistische Einheitspartei Deutschlands, SED) was the governing Marxist–Leninist political party of the German Democratic Republic from its formation in 1946 until it was dissolved after the Peaceful Revolution in 1989.

The GDR functioned nominally as a multi-party state with the SED playing a central role. Other parties in alliance with the SED were the Christian Democratic Union, the Liberal Democratic Party, the Democratic Farmers' Party, and the National Democratic Party. In the 1980s, the SED rejected the liberalisation policies of Soviet leader Mikhail Gorbachev, such as perestroika and glasnost, which would lead to the GDR's isolation from the restructuring USSR and the party's downfall in the autumn of 1989.

The party's dominant figure from 1950 to 1971, and effective leader of East Germany, was Walter Ulbricht. In 1953, an uprising against the Party was met with violent suppression by the Ministry of State Security and the Soviet Army. In 1971, Ulbricht was succeeded by Erich Honecker who presided over a stable period in the development of the GDR until he was forced to step down during the 1989 revolution. The party's last leader, Egon Krenz, was unsuccessful in his attempt to retain the SED's hold on political governance of the GDR and was imprisoned after German reunification.
