Washington State, located in the Pacific Northwest corner of the United States, is a land of dramatic contrasts — from the rain-soaked temperate rainforests of the Olympic Peninsula to the volcanic peaks of the Cascades and the arid shrub-steppe of the east. Home to Seattle, one of America's most dynamic cities, the state blends state-of-the-art technology culture with stunning wilderness, world-class food and coffee scenes, and some of the continent's most diverse outdoor adventure.
Washington State has been inhabited for at least 16,000 years, with Indigenous peoples like the Chinook, Salish, Nez Perce, and Yakama developing rich cultures along its rivers, coasts, and mountains. European contact came with Spanish and British explorers in the 1770s-1790s, followed by the Lewis and Clark Expedition of 1804-1806. The region was initially jointly occupied by Britain and the US before the 1846 Oregon Treaty established the 49th parallel as the border, and Washington became a US territory in 1853. Statehood came in 1889, and the state's development was dramatically shaped by timber, fishing, railroad expansion, the Klondike Gold Rush (which launched Seattle's prosperity), the Boeing aerospace industry, and the rise of tech giants Microsoft and Amazon in the late 20th century.
