A shire levy was a means of military recruitment in medieval England. As opposed to a levy of noble families, a shire levy was effected within a geographical administrative area (a shire), entailing the mobilisation of able-bodied men between the ages of 16 and 60 within the shire for military duty. Shire levies were especially important for England during the Hundred Years' War, when the escalation in warfare with France increased the need for soldiers: "the king was able to rely on the military support of the nobility and of the shire levies."
