In 1986, the County Council passed a motion "setting forth the historical basis for the 'renaming' of King County in honor of Reverend Dr. Martin Luther King, Jr."; however, the motion has no legal or practical force, and the "name change" is not widely publicized in the county. The full text of the motion appears at http://www.metrokc.gov/exec/mlk/motion.htm.
