American history would have been greatly altered had the British not won the French and Indian War. The conflict was the American extension of the larger Seven Years War (by which the conflict is known in Europe). However, it was more than just a European conflict fought on a different continent. Indeed, as some historians have remarked, it really was the first American war.
The principal combatants were the French and the English. Each side was allied with different Indian tribes—the Iroquis Confederacy with the British and the Algonquin, among others, with the French. However, the majority of the fighters were colonists.
And for many of the colonists, the war was the first interaction they had with other British settlers. So, for the first time, Americans from Massachusetts met Americans from Virginia. And, for the first time, they realized that they had more in common with each other than with their British allies. This became especially true when the land that they won—what was once New France—became land for British use only and not open to colonists. For the first time, the distinct American people became angered at the government of Britain. And the result was that they began to see themselves as something not British but American. In doing so, they made one more step toward the creation of an American identity.
