Final answer:
The statement is false; the United States engaged in over 370 treaties with Indigenous peoples, with the last in 1883, not Canada since its Confederation in 1867.
Step-by-step explanation:
The statement that eleven treaties between the federal government and Indigenous peoples have been enacted since Canadian Confederation in 1867 is false. The United States, not Canada, entered into over 370 treaties with dozens of tribal nations across the country, with the last treaties concluded in 1883. These treaties were primarily centered on land acquisition for the government and were negotiated against the backdrop of removal policies, wars, assimilation, and population declines. The sovereignty of Native American tribes is recognized today, although historically, the federal government frequently failed to honor these treaties, constituting a breach of the rule of law and resulting in lost income, dignity, and traditional ways of life for Indigenous peoples.
