German language in East Germany

The German language developed differently in East Germany during its existence as a separate state from 1949 to 1990, from the German of West Germany because of significant differences in the country's political and socio-cultural environment. Additionally, from the late 1960s onwards the political leaders of the DDR were intent on affirming the independence of their state by "isolationist linguistic politics" with the objective of demarcating East Germany from West Germany by actively reducing the unity of the German language.
