when did england last go to war with france
France–United Kingdom relations After escaping and briefly threatening to restore the French Empire, Napoleon was defeated by combined British, Prussian and Dutch forces at Battle of Waterloo in June 1815. With strong British support, the Bourbon monarchy was restored and Louis XVIII was crowned King of France. The Napoleonic era was the last occasion on which Britain and France went to war with each other, but by no means marked the end of the rivalry between the two nations. Despite his final defeat, Napoleon continues to be regarded as a national hero figure in France for his numerous victories over coalised monarchies.
Seven Years' War Although Anglo-French skirmishes over their American colonies had begun with what became the French and Indian War in 1754, the large-scale conflict that drew in most of the European powers was centered on Austria's desire to recover Silesia from the Prussians. Seeing the opportunity to curtail Britain's and Prussia's ever-growing might, France and Austria put aside their ancient rivalry to form a grand coalition of their own, bringing most of the other European powers to their side. Faced with this sudden turn of events, Britain aligned itself with Prussia, in a series of political manoeuvres known as the Diplomatic Revolution. However, French efforts ended in failure when the Anglo-Prussian coalition prevailed, and Britain's rise as among the world's predominant powers destroyed France's supremacy in Europe, thus altering the European balance of power.
