Which country was the principal enemy during their rise to power?

Nazi Germany's principal enemy during its rise to power was the Weimar Republic, the democratic government that ruled Germany from 1919 to 1933. The Nazis vehemently opposed the Weimar Republic and its policies, believing it to be weak and ineffective. They blamed the republic for Germany's defeat in World War I, the harsh terms of the Treaty of Versailles, and the economic difficulties that followed.
