Burgfriedenspolitik—literally "castle peace politics" but more accurately a political policy of "party truce" — is a German term used for the political truce the Social Democratic Party of Germany and the other political parties agreed to during World War I. The trade unions refrained from striking, the SPD voted for war credits in the Reichstag and the parties agreed not to criticize the government and its war. There were several reasons for the Burgfrieden politics: the Social Democrats believed it was their patriotic duty to support the government in war; they were afraid of government repression should they protest against the war; they feared living under an autocratic Russian Czar more than the German constitutional monarchy and its Kaiser; and they hoped to achieve political reforms
