Weimar culture was the flourishing of the arts and sciences that happened in Germany during the Weimar Republic, the latter during that part of the interwar period between Germany's defeat in World War I in 1918 and Hitler's rise to power in 1933.  1920s Berlin was at the hectic center of the Weimar culture. Although not part of the Weimar Republic, some authors also include the German-speaking Austria, and particularly Vienna, as part of Weimar culture.
