The SED was created in april 1946 in the Berliner Admiralspalast when the Soviet Union forced the Social Democratic Party of Germany (SPD) members and the Communist Party of Germany (KPD) members who lived in the Soviet-occupied parts of Germany and Berlin. After 1990, the party reformed itself as the Party of Democratic Socialism (later in 2005, the Left Party.PDS). It is still somewhat popular in parts the former East German territory, frequently winning seats at state and local elections. In the September 2005 Bundestag election the PDS was in coalition with WASG (Electoral Alternative for Labour and Social Justice), which was formed by Oskar Lafontaine who left the SPD. The PDS and WASG joined together in 2007.
