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 after the war, including the abrogation of the inequitable three-class voting system, by cooperating with the government.
