1 Germans were very patriotic and proud. 2  The Weimar Republic did not fulfill many Germanâs desire for glory. 3  World War One did not make Germans lose faith in their ability to achieve victory. 4  Treaty of Versailles: all the handicaps above were in some way or another caused by this treaty.
It seems amazing that the Weimar republic could survive so many problems. The government faced challenges from left and right wing groups not just in 1919 and 1920 but right up to 1923. Meanwhile, the economic problems, which were bad in 1919, seemed to get worse during this period until there was a crisis in 1923.olitically, in this period the Weimar Republic had to survive attacks from both the Left and the Right. The main parties supporting the Republic were the Social Democratic Party (SPD), the Catholic Centre Party and the Liberal Democratic Party. The new government of Germany, the Weimar Republic, was set up in 1919.
