Title:
French_and_Indian_War

Context:
The outcome was one of the most significant developments in a century of Anglo-French conflict. France ceded its territory east of the Mississippi to Great Britain. It ceded French Louisiana west of the Mississippi River (including New Orleans) to its ally Spain, in compensation for Spain's loss to Britain of Florida (Spain had ceded this to Britain in exchange for the return of Havana, Cuba). France's colonial presence north of the Caribbean was reduced to the islands of Saint Pierre and Miquelon, confirming Britain's position as the dominant colonial power in eastern North America.
