King Henry II of England passed the Assize of Arms in 1181 that specified that every free man in England should own a spear, a gambeson (quilted woollen coat padded with horsehair) and an iron helmet; and be liable to serve at the king's command. Those who owned land worth 10 marks had to have a hauberk instead of the gambeson, and those owning 16 marks of land had to have a coat of mail and a shield.
By 1285 a similar law was in force that added bows and arrows to the list of required weapons.
.Most of the swedish laws (from around the year 1300, most of them) specified helmet, some kind of armour (usually mail) and some kind of weapon (sword, axe, crossbow, etc.) for the militia.
