Which 1813 battle is known as the Battle of the Nations?

The 1813 battle known as the Battle of the Nations was the Battle of Leipzig.

Fought from 16 to 19 October 1813 in and around Leipzig, Saxony, it was the decisive clash of the German campaign of the War of the Sixth Coalition. Napoleon’s French army and its German allies faced a much larger coalition force from Russia, Austria, Prussia, Sweden, and several smaller states.

The battle involved roughly half a million soldiers, making it one of the largest engagements in the Napoleonic Wars up to that point. Coalition forces defeated Napoleon and forced his army to retreat west across the Rhine. The defeat also caused the Confederation of the Rhine, a bloc of German states allied with France, to collapse.

Leipzig is called the Battle of the Nations because so many European armies and national contingents fought there. It is often confused with Waterloo, which occurred in 1815 and ended Napoleon’s brief return from exile. Borodino was fought in Russia in 1812, while Dresden was a French victory earlier in 1813.
