The Weimar Republic was the democratic government established in Germany after World War I, lasting from 1919 to 1933. It was named after the city of Weimar, where the constitutional assembly took place. The republic faced numerous challenges, including economic instability, political extremism, and social unrest, which were exacerbated by the harsh terms of the Treaty of Versailles. Despite its difficulties, the Weimar Republic was a period of cultural innovation and artistic expression, known for movements like Expressionism and the Bauhaus school. However, the republic ultimately collapsed when Adolf Hitler and the Nazi Party rose to power, leading to the establishment of a totalitarian regime.
