The Weimar Government formed after World War 1 was a weak coalition government that faced significant opposition. It struggled to maintain stability and law and order due to opposition from left-wing communists and right-wing nationalist groups. The government was further weakened by having to accept the punitive terms of the Treaty of Versailles, including war guilt and territorial concessions. It struggled to effectively govern amid economic crisis and hyperinflation in the early 1920s. This created favorable conditions for Hitler and the Nazis to rise to power.
