The massacres of La Glacière that took place during 16–17 October 1791 in the Tour de la Glacière of the Palais des Papes at Avignon, then recently united to France, were an isolated and early example of violence in the opening phase of the French Revolution; the massacres are interpreted by French historians not as presaging the September massacres of 1792 and the Reign of Terror but as a last episode in the struggle between partisans and advocates of the reunion of the papal enclave of Avignon and the Comtat Venaissin with the state of France.
