King County, Washington

King County, Washington
King County is located in the U.S. state of Washington. The population was 2,269,675 in the 2020 census, making it the most populous county in Washington, and the 13th-most populous in the United States. The county seat is Seattle, also the state's most populous city.
Originally named after US representative William R. King in 1852, in 1985 the county ammended it's designation and logo to honor Martin Luther King Jr., a prominent civil rights activist during the Civil Rights Movement. It is one of three Washington counties that are included in the Seattle–Tacoma–Bellevue metropolitan statistical area. (The others are Snohomish County to the north, and Pierce County to the south.) About two-thirds of King County's population lives in Seattle's suburbs.
History
When Europeans arrived in the region that would become King County, it was inhabited by several Coast Salish groups. Villages around the site that would become Seattle were primarily populated by the Duwamish people. The Snoqualmie Indian Tribe occupied the area that would become eastern King County. The Green River and White River were home for the Muckleshoot tribal groups. In the first winter after the Denny Party landed at Alki Point, the settlement at the point consisted of a few dozen settlers and over a thousand Native Americans. The local tribes provided the settlers with construction labor, domestic service, and help with subsistence activities.
On December 22, 1852 the Oregon Territory legislature formed King County out of territory from within Thurston County. The county was named after Alabamian William R. King, who had just been elected Vice President of the United States under President Franklin Pierce. Seattle was made the county seat on January 11, 1853. The area became part of the Washington Territory when it was created later that year.
King County originally extended to the Olympic Peninsula. According to historian Bill Speidel, when peninsular prohibitionists threatened to shut down Seattle's saloons, Doc Maynard engineered a peninsular independence movement; King County lost what is now Kitsap County but preserved its entertainment industry.
Coal was discovered in 1853 by M. Bigelow along the Black River, and in subsequent decades several companies formed to mine coal around Lake Washington and deliver it to Seattle. The Seattle and Walla Walla Railroad started servicing the Renton coal fields in 1877, and the Newcastle fields in 1878. By 1880, King County produced 22% of the coal mined on the West Coast, most of that coal being found within the Renton Formation's Muldoon coal seam.
Name
On February 24, 1986, the King County Council approved a motion to rename the county to honor civil rights leader Martin Luther King Jr. (no relation to William R. King), preserving the name "King County" while changing its namesake. The motion stated, among other reasons for the change, that "William Rufus DeVane King was a slaveowner" who "earned income and maintained his lifestyle by oppressing and exploiting other human beings," while Martin Luther King's "contributions are well-documented and celebrated by millions throughout this nation and the world, and embody the attributes for which the citizens of King County can be proud, and claim as their own."
Because only the state can charter counties, the change was not made official until April 19, 2005, when Governor Christine Gregoire signed into law Senate Bill 5332, which provided that "King county is renamed in honor of the Reverend Doctor Martin Luther King, Jr." effective July 24, 2005.
The County Council voted on February 27, 2006, to adopt the proposal sponsored by Councilmember Larry Gossett to change the county's logo from an imperial crown to an image of Martin Luther King Jr. On March 12, 2007, the new logo was unveiled. The new logo design was developed by the Gable Design Group and the specific image was selected by a committee consisting of King County Executive Ron Sims, Council Chair Larry Gossett, Prosecutor Norm Maleng, Sheriff Sue Rahr, District Court Judge Corrina Harn, and Superior Court Judge Michael Trickey. The same logo is used in the flag.
Martin Luther King Jr. had visited King County once, for three days in November 1961.

King County is represented in the United States Congress through a near-entirety of the population in the 7th and 9th Congressional Districts, a majority of the population in the 8th Congressional District and a plurality of the population in the 1st Congressional District. In the state legislature, King contains the entirety of the 5th, 11th, 33rd, 34th, 36th, 37th, 41st, 43rd, 45th, 46th, 47th, and 48th legislative districts as well as the near-entirety of the 30th legislative district, about one-half of the 32nd legislative district, about one-third of the 1st and 31st legislative district, and a mere 627 people in the 39th legislative district. The only legislative districts represented by Republicans that include any part of King County are the 31st and 39th districts.
The people of King County voted on September 5, 1911, to create a Port District. King County's Port of Seattle was established as the first Port District in Washington State. The Port of Seattle is King County's only Port District. It is governed by five Port Commissioners, who are elected countywide and serve four-year terms. The Port of Seattle owns and operates many properties on behalf of King County's citizens, including Sea-Tac International Airport; many seaport facilities around Elliott Bay, including its original property, publicly owned Fishermen's Terminal, home to the North Pacific fishing fleet and the largest homeport for fishermen in the U.S. West Coast; four container ship terminals; two cruise ship terminals; the largest grain export terminal in the U.S. Pacific Northwest; three public marinas; 22 public parks; and nearly 5,000 acres of industrial lands in the Ballard-Interbay and Lower Duwamish industrial centers.

Politics
King County and Seattle are strongly liberal; the area is a bastion for the Democratic Party. No Republican presidential candidate has garnered the majority of the county's votes since Ronald Reagan's landslide reelection victory in 1984. In the 2008 election, Barack Obama defeated John McCain in the county by 42 percentage points, a larger margin for the Democrats than that seen in any previous election up to that point in time. Slightly more than 29% of Washington state's population reside in King County, making it a significant factor for the Democrats in a few recent close statewide elections. In the 2000 Senate elections, King County's margin of victory pushed Maria Cantwell's total over that of incumbent Republican Slade Gorton, defeating and unseating him in the United States Senate. In 2004, King County gave a lead to Democrat Christine Gregoire in her 2004 victory gubernatorial election, pushing her ahead of Republican Dino Rossi, who led by 261 votes after the initial count. Rossi resided in the county at the time of the election, in Sammamish. In the 2020 presidential election, Joe Biden defeated Donald Trump by earning 75% of King County votes. Governor Jay Inslee also defeated Republican challenger Loren Culp with 74% of the King County vote in the concurrent gubernatorial election. These were the largest margins by any candidate in a presidential race and a gubernatorial race since the county's creation.
In 2004, voters passed a referendum reducing the size of the County Council from 13 members to 9. This resulted in all council seats ending up on the 2005 ballot.
Some residents of eastern King County have long desired to secede and form their own county. This movement was most vocal in the mid-1990s (see Cedar County, Washington). It has recently been revived as Cascade County. According to a map published by the Seattle Times, four different geographic borders are being considered. Additional plans (see Skykomish County, Washington) also exist or have existed.
Religion
In 2010 statistics, the largest religious group in King County was the Archdiocese of Seattle, with 278,340 Catholics worshipping at 71 parishes, followed by 95,218 non-denominational adherents with 159 congregations, 56,985 LDS Mormons with 110 congregations, 25,937 AoG Pentecostals with 63 congregations, 25,789 ELCA Lutherans with 68 congregations, 24,909 PC-USA Presbyterians with 54 congregations, 18,185 Mahayana Buddhists with 39 congregations, 18,161 UMC Methodists with 50 congregations, 14,971 TEC Episcopalians with 35 congregations, and 12,531 ABCUSA Baptists with 42 congregations. Altogether, 37.6% of the population was claimed as members by religious congregations, although members of historically African-American denominations were underrepresented due to incomplete information. In 2014, King County had 944 religious organizations, the 8th most out of all US counties.
