The Golden Rule and Phoenix voyages in protest of U.S. nuclear testing in the Marshall Islands, 1958
Shortly after World War II, the United States began nuclear testing, mainly in Nevada. In September 1957, the United States announced its plan to conduct atomic testing in the Marshall Islands, starting April 5, 1958. In response to the adverse effects of the Nevada nuclear tests, the Committee for Nonviolent Action (CNVA) launched a protest to stop the United States from nuclear testing in the Marshall Islands, first by petitioning and then sailing to the test site in protest.
