Trade with the Native Americans was one reason the war started. The French wanted exclusive trade with the Native Americans without the British in the picture.
The bold line indicates the Ohio River Valley which was a cause of the war. This pasage was a big trade route for Frane that would be gone if the British took it.
James Wolfe was an important person in the French and Indian war. He died leading a successful attack that captured Quebec.
George Washington (Figure on the left in front of army) was a Colonel from Virginia in the colonies. He led multiple attacks against the French including one in Pennsylvania to push the French out of their territory.
One event during the French and Indian was the defeat the English suffered at the hands of the French at Fort Duquesne.
As an effect of the war Britain got almost all of France's land in North America. They got Canada and all last east of the Mississippi.
