This Socialist Peoples' Republic of Germany was created after WW2. Its capital is Berlin. The president (current: Wilhelm Pieck) is the head of state. The government is the Ministerrat, its head simply the Vorsitzender des Ministerrats (Otto Grotewohl), who appoints the ministers. The parliament, the Volkskammer, is elected once in five years (first free election was in 1950); they make the laws and have to approve the appointed government. Until the US interfered in 1949, the government was really controlled by the leaders of the Sozialistische Einheitspartei Deutschlands (SED) under Walter Ulbricht. The SED was founded in 1946 when the SPD was forced to unite with the KPD. In 1949, the parties split again, and Ulbricht (meanwhile “the most-hated man of Germany”) also had to resign as the head of the KPD.
Most of the economy is nationalized - only small firms and farmers with less than 100 hectars of land weren't expropriated. The new government didn't change those decisions, although they promised that there won't be any further expropriations. They also didn't change the structure of the government with its many ministries (one for each branch of the nationalized economy).
The new government is a coalition of SPD, KPD and DBD. It has the following ministries:
