The term "Weimar Republic" is used by historians to signify the democratic and republican period of Germany from 1919 to 1933. Following World War I, the republic emerged from the German Revolution in November 1918. In 1919 a national assembly convened in the city of Weimar, where a new constitution for the German Reich was written and adopted.
The first attempt to establish a liberal democracy in Germany failed with the ascent of the Nazi Party in 1933. The year 1933 is usually seen as the end of the Weimar Republic and as the beginning of the Nazi Party's "Third Reich".
