Seven Years' War (may 17, 1756 – feb 15, 1763)

Description:

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 Prussia, Portugal, Hanover, and other small German states) on one side and the Kingdom of France (including the Austrian-led Holy Roman Empire, the Russian Empire, Bourbon Spain, and Sweden) 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.
