Answer:
The French War started in 1754 and ended in 1763 which made it last 9 full years. One of the Causes of this war was because English colonists ran out of land and not only that but the French and the English both claimed the Ohio River Valley. Now this war costed so much money as it payed for the soldiers and supplies such as weapons. The French lost a lot of land as Britain took over the Ohio River and other things that the French claimed, which lead to a lot of angry Native Americans. Then the Britain start moving into forts and made new taxes that people had to pay.
