Final answer:
Some tribes in the Iroquois Confederacy supported the Americans during the Revolutionary War while others sided with the British.
Step-by-step explanation:
The statement that all of the tribes in the Iroquois Confederacy maintained neutrality during the Revolutionary War is False.
During the Revolutionary War, the Iroquois Confederacy was actually divided in their loyalties. While some tribes, such as the Oneida and Tuscarora, supported the Americans, others, like the Mohawk and Seneca, sided with the British. These divisions led to conflicts among the tribes themselves.
