The siege of Paris was an assault undertaken in September 1429 during the Hundred Years' War by the troops of the recently crowned King Charles VII of France, with the notable presence of Joan of Arc, to take the city held by the English and their Burgundian partisans. King Charles's French troops failed to enter Paris, defended by the governor Jean de Villiers de L'Isle-Adam and the provost Simon Morhier, with the support of much of the city's population.
