The Kamloops area was not exclusively inhabited by the Secwepemc (Showup) nation (part of the Interior Salish language group) prior to the arrival of European settlers. The Cree-Salteaux band led by Chief Yawassannay had migrated to this region in the early 15th century. The Yawassanay band's Kamloops settlement was the largest of their three tribal areas.

Relations between Nicola and the fur traders were often tense but in the end Nicola was recognised as a great help to the influx of whites during the gold rush, though admonishing those who had
