Final answer:
The claim that all tribes of the Iroquois Confederacy were neutral during the Revolutionary War is false; they were divided. The Treaty of Paris ignored Native American interests, and many tribes had previously sided with the British, fearing American expansion.
Step-by-step explanation:
The statement that all of the tribes in the Iroquois Confederacy maintained neutrality during the Revolutionary War is false. Different tribes within the Confederacy chose different sides during the war, with some siding with the Americans and others with the British.
The Treaty of Paris, which officially ended the war, largely ignored the Native American tribes and their interests, leading to further loss of land and rights in the aftermath. Additionally, Native American tribes often allied with colonial powers, with many siding with the British during the Revolutionary War because they feared American expansion would lead to greater loss of land.
