Iroquois
The Iroquois League has also been called the Iroquois Confederacy.  Some modern scholars now think the League and the Confederacy are different. According to this belief, the term "Iroquois League" stands for the ceremonies and culture found in the Grand Council, while the term "Iroquois Confederacy" stands for what was the spread out political and diplomatic group that was made after Europeans began colonizing America. The League still exists.  The Confederacy broke up after the defeat of the British and allied Iroquois nations in the American Revolutionary War.
