What impact did the early settlers have on native americans? what were the causes and effects of the french indian war?

It was a bit confusing at first. There wasn't all out war against the Native Americans it was a pain because there were so many Native American tribes and with the settlers being so new they didn't know the difference between them until it was more often too late.
The causes of the French and Indian war were things like america being rivals with France, and unlike common thought it wasn't the French against the Native Americans it was actually the French and Native Americans against the early Americans. The effects were things like the Indian Removal Act all out war against Indians and other things like that.
