The traditional ways were also disrupted and changed forever by the federal government's Indian Act, which governed First Nations people in Canada. The central purpose of the act was to assimilate aboriginal people into mainstream society. This plan was set in motion by such actions as enfranchisements (the loss of one's status) and residential schools. As well, the government sought to control the lives of First Nations people by operating their governments and dictating how every little aspect of their existence would unfold.
In 1947, the Department of Indian Affairs arrived in Carcross, changing the way of life known to the Tagish and Inland Tlingit people.
The potlatch was outlawed from 1884 to 1951, making it against the law to participate. In the Yukon, the potlatch went from being a large, dynamic event to being a quiet, subdued one as it went underground.
