In 1670, following the arrival of the Hudson's Bay Company in Eastern Canada, guns began making their way westward as trade goods and the Algonquian speaking Cree began pushing the Athapaskan speakers Dunne-za or Beaver further west. The Beaver in turn pushed the Sekani deep into the Rocky Mountain Trench in the mid-18th century. A truce was eventually agreed to by the Cree and the Beaver and the great river they called Unchagah (the Peace River) became the boundary between their hunting territories.
