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.
Sonderweg
After Germany's defeat in World War II in 1945, the term lost its positive connotations from the 19th century and acquired its present negative meaning. There was much debate about the origins of this "German catastrophe" (as the German historian Meinecke titled his 1946 book) of Nazi Germany's rise and fall. Since then, scholars have examined developments in intellectual, political, social, economic and cultural history to investigate why German democracy failed during the Weimar Republic and which factors led to the rise of National Socialism. In the 1960s, many historians concluded that the failure of Germany to develop firm democratic institutions in the 19th century had been decisive for the failure of the Weimar Republic in the 20th century.
