Seattle (47.606N. -122.33W) with a population 621,000 in 2012, is the largest city in the American state of Washington and in the Pacific Northwest. It was named after Chief Sealth, a Suqamish/Duwamish Native American leader. It was officially incorporated in 1889, but had been a town since 1851, when a group of pioneers from Illinois settled West Seattle, a peninsula within the current city limits to the west. From about 1960 until about 2000, the population remained relatively static, just under 600,000. However, the population increased into the suburbs north toward Everett, south toward Seatac and Tacoma and east (across Lake Washington) to Mercer Island, Kirkland, Redmond, Bellevue and Issaquah. As fuel prices have increased and zoning has allowed more growth, Seattle has grown about 40,000 in the last 6 years.
Seattle is "a very liberal city". Seattle is the least churched city in America, and Washington State has the highest concentration of people who say they have no religion, including athiests & agnostics.  The Pacific Northwest as a region features the lowest amount of religious people.

Many people have flocked to the Seattle area to work in what's called the "knowledge economy."
In 1999 Seattle hosted the WTO at the Washington Convention Center on Pine Street, and found itself the locus of a large protest by anti-globalist activists. Very rapidly, however, anarchists took advantage of the fact that the police were overwhelmed and began destroying property and looting storefronts. The violence of the "Battle of Seattle" raged for several days.
On Ash Wednesday 2001, Seattle sustained damage in the large Nisqually Quake, which cracked the Highway 99 Viaduct and destroyed some vintage brick buildings in Pioneer Square.

Seattle is the home of the NFL's Seattle Seahawks, the NBA's Seattle SuperSonics, the WNBA's Seattle Storm, Major League Baseball's Seattle Mariners, and the WHL hockey team Seattle Thunderbirds.

On January 11, 2013, it was announced that the Sacramento Kings of the NBA had been sold by previous owners the Maloof family to Seattle investors Chris Hansen and Steve Ballmer, who plan to move the team to Seattle and rename it as the SuperSonics.
