Seattle is a coastal seaport city and the seat of King County, in the U.S. state of Washington. With an estimated 634,535 residents as of 2012, Seattle is the largest city in the Pacific Northwest region of North America and one of the fastest-growing cities in the United States. The Seattle metropolitan area of around 3.5 million inhabitants is the 15th largest metropolitan area in the United States. The city is situated on a narrow isthmus between Puget Sound and Lake Washington, about 100 miles south of the Canada–United States border. A major gateway for trade with Asia, Seattle is the 8th largest port in the United States and 9th largest in North America in terms of container handling.The Seattle area had been inhabited by Native Americans for at least 4,000 years before the first permanent European settlers. Arthur A. Denny and his group of travelers, subsequently known as the Denny Party, arrived at Alki Point on November 13, 1851. The settlement was moved to its current site and named "Seattle" in 1853, after Chief Si'ahl of the local Duwamish and Suquamish tribes.Logging was Seattle's first major industry, but by the late 19th century the city had become a commercial and shipbuilding center as a gateway to Alaska during the Klondike Gold Rush. By 1910, Seattle was one of the 25 largest cities in the country. However, the Great Depression severely damaged the city's economy. Growth returned during and after World War II, due partially to the local Boeing company, which established Seattle as a center for aircraft manufacturing. The city developed as a technology center in the 1980s, with companies like Amazon.com, Microsoft and T-Mobile US based in the area. The stream of new software, biotechnology, and Internet companies led to an economic revival, which increased the city's population by almost 50,000 between 1990 and 2000. Since then, Seattle has become a hub for "green" industry and a model for sustainable development.Seattle has a noteworthy musical history. From 1918 to 1951, there were nearly two dozen jazz nightclubs along Jackson Street from the current Chinatown/International District to the Central District. The jazz scene developed the early careers of Ray Charles, Quincy Jones, Ernestine Anderson and others. Seattle is also the birthplace of rock legend Jimi Hendrix and the alternative rock music style known as grunge, which was made famous by local groups Nirvana, Pearl Jam, Soundgarden, and Alice in Chains. Seattle is also famous for its hip hop artists, such as rappers Sir Mix-a-Lot, Blue Scholars, Sadistik, Grieves and Macklemore.
