Pierre de Murat de Cros

Pierre de Murat de Cros, O.S.B., was a French monk of aristocratic origins who became a cardinal of the Avignon Obedience during the Great Schism, as well as the Archbishop of Arles and the Chamberlain of the Apostolic Camera. Refusing from the day of his election to support Bartolomeo Prignano after the Papal Conclave of 1378, de Cros played a critical role in delivering a considerable portion of the Roman Curia to the rival claimant Robert of Geneva, who took the name Clement VII. Historian Daniel Williman calls Murat de Cros's actions a "counter-coup".
