Germans, both high- and low-born, to envision a Central Europe free of Napoleon's influence. The creation of student militias such as the Lützow Free Corps exemplified this tendency. The debacle in Russia loosened the French grip on the German princes. In 1813, Napoleon mounted a campaign in the German states to bring them back into the French orbit; the subsequent War of Liberation culminated in the great Battle of Leipzig, also known as the Battle of Nations. In October 1813, more than 500,000 combatants engaged in ferocious fighting over three days, making it the largest European land battle of the 19th century. The engagement resulted in a decisive victory for the Coalition of Austria, Prussia, Russia, Saxony, and Sweden. As a result, the Confederation of the Rhine collapsed and the French period came to an end. Success encouraged the Coalition forces to pursue Napoleon across the Rhine; his army and his government collapsed, and the victorious Coalition incarcerated Napoleon on Elba. During the brief Napoleonic restoration known as the 100 Days of 1815, forces of the Seventh Coalition, including an Anglo-Allied army under the command of the Duke of Wellington and a Prussian army under the command of Gebhard von Blücher, were victorious at Waterloo (18 June 1815). The critical role played by Blücher's troops, especially after having to retreat from the field at Ligny the day before, helped to turn the tide of combat against the French. The Prussian cavalry pursued the defeated French in the evening of 18 June, sealing the allied victory. From the German perspective, the actions of Blücher's troops at Waterloo, and the combined efforts at Leipzig, offered a rallying point of pride and enthusiasm. This interpretation became a key building block of the Borussian myth expounded by the pro-Prussian nationalist historians later in the 19th century. Congress of Vienna and the rise of German dualism After Napoleon's defeat, the Congress of Vienna established a new European political-diplomatic system based on the balance of power. This system reorganized Europe into spheres of influence, which, in some cases, suppressed the aspirations of the various nationalities, including the Germans and Italians. Generally, an enlarged Prussia and the 38 other states consolidated from the mediatized territories of 1803 were confederated within the Austrian Empire's sphere of influence. The Congress established a loose German Confederation (1815–1866), headed by Austria, with a "Federal Diet" (called the Bundestag or Bundesversammlung, an
