Which significant battle took place in 1815?

The Battle of Waterloo, fought in 1815, is significant as it marked the end of the Napoleonic Wars and led to the defeat of French Emperor Napoleon Bonaparte. This battle took place on June 18, 1815, and involved a coalition of British-led forces under the Duke of Wellington and Prussian troops commanded by Gebhard Leberecht von Blücher confronting Napoleon's army. The outcome of the battle significantly altered the political landscape of Europe and established a new balance of power, leading to a period of relative peace known as the Congress of Vienna.

In contrast, the Battle of Hastings occurred in 1066 and was crucial for the Norman Conquest of England. The Battle of Bosworth, fought in 1485, was a key battle that ended the Wars of the Roses. Lastly, the Battle of Blenheim took place in 1704 during the War of the Spanish Succession. Each of these battles was important in its own historical context, but they do not align with the year 1815 like the Battle of Waterloo does.
