Thurston County was created out of Lewis County by the government of Oregon Territory on January 12, 1852. At that time, it covered all of the Puget Sound region and the Olympic Peninsula. On December 22 of the same year, Pierce, King, Island, and Jefferson Counties were split off from Thurston County. Thurston County is located in Western Washington, on the southern end of Puget Sound, often called the "South Sound." It is the eighth smallest county in the state, with a total land mass of 727 miles, but also the eighth most populous county, with a population of 207,355 counted in the 2000 United States Census. Thurston County is named after Samuel R. Thurston, in 1849 the first delegate to Congress from the new Oregon Territory, part of which later became Washington. In 1845 the county became the site of the first American settlement in the future state of Washington when Michael Simmons (1814-1867) settled near Tumwater Falls. In 1853 the town of Olympia was chosen as the territorial (later state) capital, but battles would rage over this choice for the next century. During the county's first century lumber and its byproducts rather than state government played the leading economic role. In 1954, the Washington Supreme Court ruled that state government offices must have their headquarters in Olympia, and soon state government dominated the county's economy, while its lumber industry faded to a fraction of its former glory. Thurston County's population boomed beginning in the early 1970s, transforming the towns of Olympia, Lacey, and Tumwater into a small metropolis of its own and attracting migration from the larger cities to the north of Tacoma and Seattle.
As reported by the Census Bureau, the county has a total area of 774 square miles (2,004 km2), of which, 727
square miles (1,883 km2) of it is land and 47 square miles (121 km2) of it (6.03%) is water.
