Prussia
In 1871, most German states (notably excluding Austria and Switzerland) united to create the German Empire under Prussian leadership. In November 1918, the monarchies were abolished and the nobility lost its political power during the German Revolution of 1918–19. The Kingdom of Prussia was thus abolished in favour of a republic—the Free State of Prussia, a state of Germany from 1918 until 1933. From 1933, Prussia lost its independence as a result of the Prussian coup, when the Nazi regime was successfully establishing its Gleichschaltung laws in pursuit of a unitary state. With the end of the Nazi regime, in 1945, the division of Germany into Allied occupation zones and the separation of its territories east of the Oder–Neisse line, which were incorporated into Poland and the Soviet Union, the State of Prussia ceased to exist de facto. Prussia existed de jure until its formal abolition by the Allied Control Council Enactment No. 46 of 25 February 1947.
