Burgfriedenspolitik
The Burgfriedenspolitik (German: [ˈbʊʁkfʁiːdn̩s.poliˌtiːk], lit. 'castle peace policy') was a political truce between the German Empire's parliamentary parties during World War I. They agreed not to criticise the government's handling of the war, to keep their disagreements out of public view and to postpone elections until after the end of the war. In addition, three major associations of trade unions promised not to strike.
