History of Germany during World War I
In November 1918, with internal revolution, a stalemated war, Bulgaria and the Ottoman Empire suing for peace, Austria-Hungary falling apart from multiple ethnic tensions, and pressure from the German high command, the Kaiser and all German ruling princes abdicated. On 9 November 1918, the Social Democrat Philipp Scheidemann proclaimed a Republic, in cooperation with the business and middle classes, not the revolting workers. The new government led by the German Social Democrats called for and received an armistice on 11 November 1918; in practice it was a surrender, and the Allies kept up the food blockade to guarantee an upper hand. The war was over; the history books closed on the German Empire. It was succeeded by the democratic, yet flawed, Weimar Republic.
German Empire
The defeat and aftermath of the First World War and the penalties imposed by the Treaty of Versailles shaped the positive memory of the Empire, especially among Germans who distrusted and despised the Weimar Republic. Conservatives, liberals, socialists, nationalists, Catholics and Protestants all had their own interpretations, which led to a fractious political and social climate in Germany in the aftermath of the empire's collapse.
Under Bismarck, a united German state had finally been achieved, but it remained a Prussian-dominated state and did not include German Austria as Pan-German nationalists had desired. The influence of Prussian militarism, the Empire's colonial efforts and its vigorous, competitive industrial prowess all gained it the dislike and envy of other nations. The German Empire enacted a number of progressive reforms, such as Europe's first social welfare system and freedom of press. There was also a modern system for electing the federal parliament, the Reichstag, in which every adult man had one vote. This enabled the Socialists and the Catholic Centre Party to play considerable roles in the empire's political life despite the continued hostility of Prussian aristocrats.
