King County, Washington (Map It) was created on December 22, 1852 from Thurston County. The county was named in honor of William R. King (1786–1853), U.S. Vice President under Franklin Pierce; officially renamed in 1986 after Martin Luther King, Jr. (1929–1968). The first settlements in the county were the donation land claims of Luther Collins, Henry Van Asselt, and Jacob Maple in September of 1851 in the Duwamish Valley area of present day Seattle. This settlement was followed in November by one led by David Denny and Leander Terry at Alki Pont. The next year the Denny-Terry settlers moved to a better location for loading lumber on the east side of Elliott Bay and named the settlement Seattle after the friendly chief of the Duwamish Indians. The next year Henry Yesler set up the first steam sawmill on Puget Sound. Learn More About State of Washington History.
