What made the Weimar Republic so unstable, apart from the lack of support by the German population?
First, the Allied victors of World War I did not provide enough economic, political, or educational support for the new republic, but instead undermined it by insisting on their extremely high demands for reparations and acceptance of “guilt.” Second, the Weimar constitution had severe flaws, such as admitting too many parties into the political process or giving the Reichs-President too many powers—particularly in light of the fact that this position was later occupied by an explicit opponent of the republic (i.e., von Hindenburg).
