During the High Middle Ages (c. 1000–1300), Christian-oriented art and architecture flourished and the Crusades were mounted to recapture the Holy Land from Muslim control. The influence of the emerging nation-state was tempered by the ideal of an international Christendom and the presence of the Roman Catholic Church in all western kingdoms. The codes of chivalry and courtly love set rules for proper behavior, while the Scholastic philosophers attempted to reconcile faith and reason. The age of Feudalism would be dramatically transformed by the cataclysm of the Black Death and its aftermath. This time would be a major underlying cause for the Renaissance. By the turn of the 16th century European or Western Civilization would be engaging in the Age of Discovery.
