German Unification (1866–1871):
In 1848, the Frankfurt Parliament attempted to unify Germany on liberal-constitutional principles, but failed when King Friedrich Wilhelm IV of Prussia rejected the crown and monarchs opposed the assembly. Troops dissolved the parliament.
Subsequently, Prussia, under Chief Minister Otto von Bismarck, led unification through military power rather than popular movements. Prussia defeated Austria (1866) and France (1871). On 18 January 1871, princes, army representatives, and ministers gathered in the Hall of Mirrors, Versailles, and proclaimed the German Empire headed by Kaiser William I. The new state modernised currency, banking, legal and judicial systems, with Prussian practices becoming the model for all Germany.
