The French and Indian War is an extension of the Seven Years’ War of 1756-63 that pitted the colonies of British America against New France. The French were defeated and lost vast territories, including Canada and French Louisiana. The Brits gained land east of the Mississippi River and removed French threat to its thirteen colonies. The conflict trained many American officers, including Washington, that would later fight in the Revolutionary War. The Brits Empire grew substantially, but the war incurred great debts. The Brits tried to tax the colonies more in order to pay the debt, causing the colonies to unite just in time for the Revolutionary war.
