Key political events during the Weimar Republic included hyperinflation, the rise of extremist political parties, and the signing of the Treaty of Versailles. Established in 1919 after World War I, the republic faced significant economic challenges, particularly severe hyperinflation in the early 1920s, leading to public discontent and loss of confidence in democratic governance. The economic instability enabled the rise of the Nazi Party and other radical factions, culminating in the 1933 appointment of Adolf Hitler as Chancellor. The era is characterized by social turmoil, political fragmentation, and ultimately the collapse of democratic institutions.
