Écorcheurs
The écorcheurs (literally "flayers") were armed bands who desolated France in the reign of Charles VII, stripping their victims of everything, often to their very clothes.
They were mercenaries without employment since the Treaty of Arras which ended disputes between the Armagnacs and Burgundians in 1435. Rodrigo de Villandrando was known as the "Emperor of Pillagers" (empereur des brigands) and "L'Écorcheur" (the slaughterer).
