The Communist Party of Germany (KPD) and the east German branches of the Social Democratic Party of Germany (SPD) merged to form the Socialist Unity Party of Germany (SED) on 21 April 1946. Although nominally a merger of equals, the merged party quickly fell under Communist domination and developed along lines similar to other Communist Parties in what became the Eastern Bloc. The SED would be the only party of the German Democratic Republic until the end of the republic in December 1989. In the course of the merger, about 5,000 Social Democrats who opposed it were detained and sent to labour camps and jails.[1]
