 The current archaeological evidence indicates that the largest known village had a population of about 1,000 and their total population was 8,000–10,000.The traditional view is that they disappeared because of late 16th-century warfare by the Mohawk nation of the "Haudenosaunee" or Iroquois League, which wanted to control trade with Europeans in the valley.Knowledge about the St. Lawrence Iroquoians has been constructed from the studies of surviving oral accounts of the historical past from the current Native people, writings of the French explorer Jacques Cartier, earlier histories, and anthropologists' and other scholars' work with archaeological and linguistic studies since the 1950s.
