The Great Peace March for Global Nuclear Disarmament, Inc. (also referred to as The Great Peace March, GPM, and the March) was a cross-country event in 1986 aimed at raising awareness to the growing danger of nuclear proliferation and to advocate for complete, verifiable elimination of nuclear weapons from the earth. The GPM consisted of hundreds of people, mostly but not exclusively Americans, who convened in Los Angeles, California, United States, in February 1986 to walk from L.A. to Washington, D.C., the nation's capital. The group left Los Angeles on March 1, 1986 and arrived in Washington, D.C. on November 15, 1986, a journey of about 3,700 miles, nine months, and many campsites.
