Which coalition played a crucial role in the defeat of Napoleon at Waterloo?

The Seventh Coalition was instrumental in defeating Napoleon at the Battle of Waterloo in 1815. This coalition, formed after Napoleon escaped from exile on Elba and returned to power in France, brought together several major European powers, including Britain, the Netherlands, Prussia, and other allies. The combined forces of these nations were critical in gathering the manpower and resources necessary to confront and ultimately defeat Napoleon's army.

The significance of the Seventh Coalition lies in its unity and the strategic coordination of its forces. The Duke of Wellington commanded the allied forces from Britain, while Gebhard Leberecht von Blücher led the Prussians. Their collaboration during the battle, along with the timely arrival of Prussian reinforcements, played a decisive role in tipping the scales against Napoleon. The defeat at Waterloo marked the end of the Napoleonic Wars and led to Napoleon's final exile to Saint Helena.

In contrast, the other coalitions mentioned were active in previous conflicts against Napoleon before his initial exile, such as the Third, Fourth, and Fifth Coalitions. While they contributed to the broader struggle against Napoleonic expansion, it was the Seventh Coalition that specifically achieved victory at Waterloo.
