Seattle is a coastal seaport city and the seat of King County, in the U.S. state of Washington. With an estimated 652,405 residents as of 2013, Seattle is the largest city in the Pacific Northwest region of North America and the fastest-growing major city in the United States. The Seattle metropolitan area of around 3.6 million inhabitants is the 14th largest metropolitan area in the United States. The city is situated on a narrow isthmus between Puget Sound (an inlet of the Pacific Ocean) and Lake Washington, about 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 previously 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.
