Washington is a state in the Pacific Northwest region of the United States located north of Oregon, west of Idaho, and south of the Canadian province of British Columbia on the coast of the Pacific Ocean. Named after George Washington, the first President of the United States, the state was made out of the western part of the Washington Territory which had been ceded by Britain in 1846 by the Oregon Treaty as a settlement of the Oregon Boundary Dispute. It was admitted to the Union as the 42nd state in 1889. Washington is often referred to as Washington State or the State of Washington to distinguish it from Washington, D.C., the capital of the United States.
