Seattle is the county seat of King County, Washington. With 608,660 residents as of the 2010 Census, Seattle is the largest city in the Northwestern United States. The Seattle metropolitan area of about 3.4 million inhabitants is the 15th largest metropolitan area in the country. The city is a major seaport situated on a narrow isthmus between Puget Sound (an arm of the Pacific Ocean) and Lake Washington, about 114 miles (183 km) south of the Canada–United States border.
The Seattle area had been inhabited by Native Americans for at least 4,000 years before the first permanent white 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 renamed “Seattle” in 1853, after Chief Seattle of the local Duwamish and Squamish tribes.
