The history of First Nations is pre-history. History of Canada’s founding peoples goes back to the earliest time. Settlement of the Americas is the subject of on-going methodologies and technologies, used by archeologist and other researchers. Most Native Americans had, historically, preserved their histories by oral traditions and art work which has resulted in the first written sources on the conflict being authored by Europeans. Europeans, at that time, had Patriarchal cultures and had individual property right. The difference in cultures, between Native Americans and Europeans, caused extensive political tension, ethnic violence and social disruption. Now, the United States and Canada saw natives suffer fatalities, such as small pox which was caused by contact with the European diseases. In 1830, the U.S. Congress passed the Indian Removal Act which meant they had to relocate the natives. Native Americans have an unique relationship with the United States, because of bands with treaty rights. Since then, they have tried to teach their language to younger generations and to have Native American studies programs and tribal schools.
