Final answer:
The statement about the Iroquois Confederacy's neutrality during the Revolutionary War is false as the Confederacy was divided during the conflict. The Treaty of Paris ignored American Indians, and the Proclamation of 1763 was a response to Pontiac's War.
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 American Revolutionary War, the Iroquois Confederacy, which was a powerful alliance of Native American nations primarily in what is now New York, was split due to conflicting interests and pressures from both British and American forces. Some nations within the Confederacy, most notably the Oneida and the Tuscarora, sided with the Americans, while others, including the Mohawk, Seneca, Onondaga, and Cayuga, sided with the British.
Regarding the treatment of American Indians in early American history, it is true that for all practical purposes, the Treaty of Paris, which ended the Revolutionary War, largely ignored the interests and rights of the American Indians. This treaty only settled matters between the colonists and the British, without considering Native American lands and sovereignty.
Another point of discussion is the Proclamation of 1763, which was indeed enacted partially in response to Pontiac's War. This proclamation aimed to stabilize relations with North American Indian tribes through regulation of trade, settlement, and land purchases on the western frontier.
