HIST 1301 Tarleton State University Native Americans and Lost Wars Discussion

I’m studying for my History class and need an explanation.

 In the seventeenth and eighteenth centuries, Native  Americans lost a string of wars to colonists (The Pequot War, King  Philip’s War, the Yamasee Uprising, and the Seven Years’ War are four  good examples). Why did Native Americans always seem to be at a  disadvantage in these wars? Which Native American group was the one  exception to this general trend? Why?
