Seattle is a West Coast seaport city and the seat of King County. With an estimated 662,400 residents as of 2015, Seattle is the largest city in both the state of Washington and the Pacific Northwestregion of North America.
Archaeological excavations suggest that Native Americans have inhabited the Seattle area for at least 4,000 years.By the time the first European settlers arrived, the people (subsequently called the Duwamish tribe) occupied at least seventeen villages in the areas around Elliott Bay.The first European to visit the Seattle area was George Vancouver, in May 1792 during his 1791–95 expedition to chart the Pacific Northwest.The name "Seattle" appears on official Washington Territory papers dated May 23, 1853, when the first plats for the village were filed. In 1855, nominal land settlements were established. On January 14, 1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of trustees managing the city. The town of Seattle was disincorporated January 18, 1867 and remained a mere precinct of King County until late 1869, when a new petition was filed and the city was re-incorporated December 2, 1869 with a Mayor-council government.The corporate seal of the City of Seattle carries the date "1869" and a likeness of Chief Sealth in left profile.
