Kaiser's Germany 1914,
"As a legislative body, the Reichstag had no say in the decision to declare war first on Russia and then on France. In fact, it was not even in session when the war began."

"At the beginning of World War I, Germany was a constitutional monarchy in which political parties were limited to the legislative arena. They could control neither the government nor the military. At the end of the war, the political system had been transformed into a – albeit short-lived – parliamentary monarchy in which the political and military branches of the executive were designed to be fully responsible to the Reichstag and in which members of the legislative branch were able to serve in government as well.
