John and William Merfold were yeomen brothers in Sussex, England, in the mid 15th-century. Both were indicted in 1451 for publicly inciting the killing of the nobility, clergy, and the deposition of King Henry VI. They also advocated rule by common people. Minor uprisings spread throughout Sussex until authorities intervened and four yeomen were hanged. The actions of the Merfolds followed a major rebellion in Kent in 1450 led by Jack Cade. They are considered demonstrative of underlying class and social conflicts in England during the 15th century.
