Cayuse

The Cayuse were a Indigenous people of the northwestern U.S., primarily located in eastern Oregon and Washington. They are now part of the Confederated Tribes of the Umatilla Indian Reservation in northeastern Oregon.1

The term "cayuse" also refers to a type of horse native to North America. These horses are descended from those brought by the Spanish in the 16th century and are known for their speed and endurance. The Cayuse people placed a high value on horses, possessing more than many Plains tribes by the early 19th century.23
