History of the Volkspolizei
The Volkspolizei (German for "People's Police") served as the armed forces and the national police of the German Democratic Republic (East Germany) from 1946 to 1956. The Volkspolizei was responsible for most law enforcement in East Germany, but because of its organisation and structure it was also considered a paramilitary force.
