Seven Years' War

The Seven Years' War (known also as the War of the Conquest) was an armed military conflict that was fought from 1754 to 1763 between several nations in Europe, most notably Great Britain and France. Other belligerents included Portugal, Spain, Russia, Prussia, Austria, and, in North America, several Iroquois tribes. 

The war began in 1754 as the result of shifting political borders and alliances in Europe, coupled with the efforts of several nations to secure lands beyond Britain's Thirteen Colonies. Fighting soon broke out both in Europe and in and around North America; theaters ranged from Canada to the West Indies and from the eastern Atlantic coast to the Russian city of Moscow. The infamous French and Indian War was part of the conflict, specifically the North American theater, where French forced allied with native Iroquois tribes to stop the British advance westward. In Europe, the war was largely fought with seiges and arson along with several open battles.

Several key historical figures were involved in the war, including General Edward Braddock and future United States President George Washington; the Templars Haytham Kenway, William Johnson, John Pitcairn, and Charles Lee also participated in the conflict, several of them earning reputation, influence, and power from their involvement. The Assassin-turned-Templar Shay Cormac was also active during the war. 

The war officially ended with the Treaty of Paris in 1763, granting the victorious Great Britian several holdings throughout the Americas. Spain also emerged a victor, and was given French Louisiana, among other lands.

Britain's mounting costs from the war eventually contributed to a growing colonial resentment towards England; year later, this would set the stage for the American Revolutionary War in 1775.
