Hundred Years' War (1415–53)
The Lancastrian War was the third and final phase of the Anglo-French Hundred Years' War. It lasted from 1415, when King Henry V of England invaded Normandy, to 1453, when the English lost Bordeaux. It followed a long period of peace from the end of the Caroline War in 1389. The phase was named after the House of Lancaster, the ruling house of the Kingdom of England, to which Henry V belonged.
Seven Years' War
The Seven Years' War was a global conflict fought between 1756 and 1763. It involved every European great power of the time and spanned five continents, affecting Europe, the Americas, West Africa, India, and the Philippines. The conflict split Europe into two coalitions, led by the Kingdom of Great Britain (including the Kingdom of Prussia, the Kingdom of Portugal, the Electorate of Brunswick-Lüneburg, and other small German states) on one side and the Kingdom of France (including the Austrian-led Holy Roman Empire), the Russian Empire (until 1762), the Kingdom of Spain, and the Swedish Empire on the other. Meanwhile, in India, some regional polities within the increasingly fragmented Mughal Empire, with the support of the French, tried to crush a British attempt to conquer Bengal. The war's extent has led some historians to describe it as "World War Zero", similar in scale to other world wars.
