During the Middle Ages, Medieval Europe was engaged in constant warfare. European warfare during the Middle Ages was marked by a transformation in the character of warfare from antiquity, changing military tactics, and the role of cavalry and artillery. In addition to military, tactical and technological innovations during this period, chivalric military and religious ideals arose, giving motivation for engagement in the ceaseless warfare. In the Iberian Peninsula (particularly in Spain or future Spanish territories), chivalric ideals and institutions would be adopted and exercised with more fervour than anywhere else.
