Adamite

Member of a Gnostic sect of the 2nd century in Africa, who sought to re-establish the innocent state of humanity at the time of the creation, going naked and rejecting marriage. The doctrine was prevalent among some of the Beghards, or Brethren of the Free Spirit, in 14th-century Flanders, and a similar sect appeared in Bohemia and Moravia in the 15th century. They were massacred by Siska in 1421.
