What Problems Did the Weimar Republic Face from 1918 to 1923?

In 1919 the Weimar Republic was set up in Germany. From its birth it faced numerous political problems, for which the causes were many and varied. These problems included political instability, deep divisions within society and economic crisis; problems were constantly appearing for the new government and from 1919-1923, the Weimar Republic experienced a period of crisis.
