1815 -1866 Following the fall of Napoleon, the Congress of Vienna (convened in 1814) founded the German Confederation (Deutscher Bund), a loose league of 39 sovereign states. The appointment of the Emperor of Austria as the permanent president of the Confederation reflected the Congress's failure to accept Prussia's influence among the German states, and acerbated the long-standing competition between the Hohenzollern and Habsburg interests. Disagreement within restoration politics partly led to the rise of liberal movements, followed by new measures of repression by Austrian statesman Metternich. The Zollverein, a tariff union, furthered economic unity in the German states. National and liberal ideals of the French Revolution gained increasing support among many, especially young, Germans. The Hambach Festival in May 1832 was a main event in support of German unity, freedom and democracy. In the light of a series of revolutionary movements in Europe, which established a republic in France, intellectuals and commoners started the Revolutions of 1848 in the German states. King Frederick William IV of Prussia was offered the title of Emperor, but with a loss of power; he rejected the crown and the proposed constitution, leading to a temporary setback for the movement.
