Tazewell County is a county in the U.S. state of Illinois. According to the 2010 census, it had a population of 135,394. Its county seat and largest city is Pekin. It is pronounced with a short "a", to rhyme with "razz" rather than "raze".
Tazewell County was formed out of Peoria County in 1827. The consensus appears to be that it was named in honor of Littleton Tazewell, who served in the U.S. Senate, and who became Governor of Virginia in 1834. It is, however, possible that it was named after Littleton's father, prominent Virginia politician Henry Tazewell, after whom Tazewell County, Virginia, was named.
Tazewell from the time of its creation to 1829, including a large tract of unorganized territory temporarily attached to it, whose precise border was not defined.
