second war, Queen Anne's War, the British conquered Acadia (1710). The sixth and final colonial war between the nations of France and Great Britain (1754–1763), resulted in the French giving up their claims and the British claimed the lands of Canada (New France). In this final war, the Franco-Indian alliance brought together Americans, First Nations and the French, centred on the Great Lakes and the Illinois Country. The alliance involved French settlers on the one side, and on the other side were the Abenaki, Odawa, Menominee, Ho-Chunk (Winnebago), Mississaugas, Illiniwek, Huron-Petun, Potawatomi etc. It allowed the French and the Indians to form a haven in the middle-Ohio valley before the open conflict between the European powers erupted. In the Royal Proclamation of 1763, the British recognized the treaty rights of the indigenous populations and resolved to only settle those areas purchased lawfully from the indigenous peoples. Treaties and land purchases were made in several cases by the British, but the lands of several indigenous nations remain unceded and/or unresolved. Slavery First Nations routinely captured slaves from neighbouring tribes. Sources report that the conditions under which First Nations slaves lived could be brutal, with the Makah tribe practicing death by starvation as punishment and Pacific coast tribes routinely performing ritualized killings of slaves as part of social ceremonies into the mid-1800s. Slave-owning tribes of the fishing societies, such as the Yurok and Haida lived along the coast from what is now Alaska to California. Fierce warrior indigenous slave-traders of the Pacific Northwest Coast raided as far south as California. Slavery was hereditary, the slaves and their descendants being considered prisoners of war. Some tribes in British Columbia continued to segregate and ostracize the descendants of slaves as late as the 1970s. Among Pacific Northwest tribes about a quarter of the population were slaves. The citizens of New France received slaves as gifts from their allies among First Nations peoples. Slaves were prisoners taken in raids against the villages of the Fox nation, a tribe that was an ancient rival of the Miami people and their Algonquian allies. Native (or "pani", a corruption of Pawnee) slaves were much easier to obtain and thus more numerous than African slaves in New France, but were less valued. The average native slave died at 18, and the average African slave died at 25 (the average European could expect to live until the age of 35).
