to seek written permission from an Indian Agent before leaving their reserves for any length of time. Indigenous people regularly defied those laws, as well as bans on Sun Dances and potlatches, in an attempt to practice their culture. The 1930 Constitution Act or Natural Resources Acts was part of a shift acknowledging indigenous rights. It enabled provincial control of Crown land and allowed Provincial laws regulating game to apply to Indians, but it also ensured that "Indians shall have the right ... of hunting, trapping and fishing game and fish for food at all seasons of the year on all unoccupied Crown lands and on any other lands to which the said Indians may have a right of access." First and Second World Wars More than 6,000 First Nations, Inuit and Métis served with British forces during First World War and Second World War. A generation of young native men fought on the battlefields of Europe during the Great War and approximately 300 of them died there. When Canada declared war on Germany on September 10, 1939, the native community quickly responded to volunteer. Four years later, in May 1943, the government declared that, as British subjects, all able Indian men of military age could be called up for training and service in Canada or overseas. Late 20th century Following the end of the Second World War, laws concerning First Nations in Canada began to change, albeit slowly. The federal prohibition of potlatch and Sun Dance ceremonies ended in 1951. Provincial governments began to accept the right of Indigenous people to vote. In June 1956, section 9 of the Citizenship Act was amended to grant formal citizenship to Status Indians and Inuit, retroactively as of January 1947. In 1960, First Nations people received the right to vote in federal elections without forfeiting their Indian status. By comparison, Native Americans in the United States had been allowed to vote since the 1920s. 1969 White Paper In his 1969 White Paper, then-Minister of Indian Affairs, Jean Chrétien, proposed the abolition of the Indian Act of Canada, the rejection of Aboriginal land claims, and the assimilation of First Nations people into the Canadian population with the status of "other ethnic minorities" rather than as a distinct group. Harold Cardinal and the Indian Chiefs of Alberta responded with a document entitled "Citizens Plus" but commonly known as the "Red Paper". In it, they
