In the mid 19th century, the formerly nomadic aboriginal tribes in North Central Washington began to settle along prominent waterways to trade with Canadian and European explorers and settlers. It was not long before disputes over land ownership between natives and newcomers became common. In 1872, President Ulysses S. Grant signed an Executive Order establishing the Colville Indian Reservation along the Columbia River, where Native Americans from 12 tribes were designated to live on several million acres of land. Twenty years later, the reservation was reduced to 1.4 million acres.
