Final answer:
It's false that all tribes of the Iroquois Confederacy remained neutral during the Revolutionary War as the Confederacy was divided. The Proclamation of 1763 was a response to Pontiac's War and the Treaty of Paris ignored the American Indians. Land acquisition was a key factor in early U.S. Indian policy.
Step-by-step explanation:
The statement that all of the tribes in the Iroquois Confederacy maintained neutrality during the Revolutionary War is false. The Iroquois Confederacy, also known as the Haudenosaunee, was split in its loyalties during the war. Some of the tribes within the Confederacy, such as the Oneida and the Tuscarora, supported the American cause, while others, including the Mohawk, Seneca, Onondaga, and Cayuga, sided with the British. This division led to internal conflicts and contributed to the dispersal of the Confederacy after the war.
Additionally, the Proclamation of 1763 was indeed a response to Pontiac's War and aimed to stabilize relations between Native Americans and settlers by restricting colonial expansion westward. The Treaty of Paris, which ended the Revolutionary War, largely ignored the American Indians, failing to secure protection for their lands or political rights.
The early U.S. Indian policy was greatly influenced by the goal of land acquisition. This often resulted in treaties and policies that aimed to transfer land from Native American nations to the U.S. government and its citizens.
