Guillaume Cale

Guillaume Cale (sometimes anglicized to William Kale, also known as Guillaume Caillet, popularly known as Jacques Bonhomme ("Jack Goodfellow") or Callet) was a wealthy peasant from the village of Mello near Beauvais, who became leader of the peasant Jacquerie which broke out in May 1358 and continued for a month unchecked until the Battle of Mello on 10 June. Cale's origins are unknown; it is not clear how old he was at the time of the uprising, nor is anything known about his family and business ties, except that he was a reasonably well-off farmer.
