The ヴァイマル共和国, or 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 ヴァイマル, where the constitutional assembly took place. The republic faced numerous challenges, including economic instability, political extremism, and social unrest, which ultimately weakened its authority. Despite its difficulties, the Weimar Republic was a period of significant cultural and intellectual development. It saw the rise of influential movements in art, literature, and philosophy, with notable figures such as トーマス・マン and ベルトルト・ブレヒト emerging during this time. However, the republic's struggles paved the way for the rise of the ナチス党 and the end of democracy in Germany.
