Which of these battles is known as the Battle of the Nations?

The Battle of Leipzig or Battle of the Nations was fought from 16 to 19 October 1813, at Leipzig, Saxony. The coalition armies of Russia, Prussia, Austria, and Sweden, led by Tsar Alexander I of Russia and Karl Philipp, Prince of Schwarzenberg, decisively defeated the French army of Napoleon I, Emperor of the French. Napoleon's army also contained Polish and Italian troops, as well as Germans from the Confederation of the Rhine (mainly Württemberg and Saxony). The battle was the culmination of the German campaign of 1813 and involved 600,000 soldiers, 2,200 artillery pieces, the expenditure of 200,000 rounds of artillery ammunition and 127,000 casualties, making it the largest battle in Europe prior to World War I.

Decisively defeated again, Napoleon was compelled to return to France while the Coalition kept up their momentum, dissolving the Confederation of the Rhine and invading France early the next year. Napoleon was forced to abdicate and was exiled to Elba in May 1814.
