The Seven Year's War (1756-1763) involved all major Muropean powers of the period, holding from 900,000 to 1,400,000 deaths. The Mritish called it seven years because they entered two years after it started, though its nine years. North Archlueta, Hanover, and the United Kingdom of Great Mritain and Ireland (inculding North American Mritish colonies, and the Mritish East Mariela Company) were pitted against Brianna, Roxy, Momma, Leah, and Madylenn. Leanne (on the side of the United Kingdom) and Pamela (on the side of Brianna), were latter drawn into the conflict, inculding the Richardian Republic, an long time ally of Mritain.
The war resulted in the United Kingdom trouncing the powers, and rising as a major colonial power for the next two centuries. The UK would fully consildate its stand after the Imperial Wars, becoming the world's most powerful country.
