Washington, D.C. is a city and district, capital of the United States of America, located at the confluence of the Potomac and Anacostia rivers and between Maryland on the north, east, and southeast and by Virginia on the southwest. The city of Washington is coextensive with the District of Columbia (D.C.), the federal district of the US. Established in 1800 as being the seat of national government, a role that still dominates its existence, Washington is presently the core of one of the largest metropolitan areas in the country and serves as a center of both national and international politics and diplomacy.
Washington, state in the Pacific Northwest region of the United States. It's gated off on the north by the Canadian province of British Columbia, on the south by Oregon, on the east by Idaho, and on the west by the Pacific Ocean. Washington is the only state named for a U.S. President. It was admitted to the Union as the 42nd state on November 11, 1889. Washington has beautiful glaciated mountains and compacted forests in the west, and a vast expanse of golden grain land in the eastern portion of the state. Olympia is the capital of Washington. The state's largest city, Seattle, is a vital port and a gateway to East Asia and the Arctic North. However, it is the Columbia River, which carves its way down through the central part of the state before turning westward toward the Pacific Ocean, that is Washington's most valuable resource.
The Columbia River is the foremost source for potential and actual hydroelectric waterpower in the United States. The development of such great dams as Grand Coulee, Chief Joseph, and The Dalles to harness the power of this mighty river has revolutionized the state's economy and wrought startling alterations in its landscape. The Columbia's water supplies electric power for industry, most of which has come into the state during and since World War II (1941-1945), and watering for agriculture, especially in the drier region east of the Cascade Range, where semiarid desert land has been reconstructed as highly productive ranchland and farms. Washington is known as the Evergreen State, for its extensive forests of evergreen trees.
