A Breed Born in Idaho
The Appaloosa breed originated in the Palouse River region of north-central Idaho and southeastern Washington, where the Nez Perce tribe developed sophisticated horse-breeding programs beginning in the early 1700s. The tribe acquired horses descended from Spanish stock that had spread north from Mexico and the Southwest. Unlike many tribes that allowed horses to breed randomly, the Nez Perce practiced selective breeding—gelding inferior stallions and breeding only the best horses for desired traits including stamina, intelligence, and the distinctive spotted coat patterns.
