The Coeur d'Alene are an American Indian tribe. During the 19th century they inhabited Idaho and Washington territories. In 1858 a part of the tribe joined in an attack on Colonel Steptoe. They were subsequently defeated by Colonel Wright and became peaceful. In 1867 a reservation was set apart for those in Idaho, and in 1872 a community living in Paradise Valley was removed to land between the Okinokane and Columbia rivers. Research Coeur d'Alene
