{{Main|Chivalry}}

During the High Middle Ages, the idea of a Christian warrior started to change as Christianity grew more prominent in Medieval Europe. The [[Chivalry|Codes of Chivalry]] promoted the ideal knight to be selfless, faithful, and fierce against those who threaten the weak.<ref>{{Cite book|last=Saul|first=Nigel|title=Chivalry in Medieval England|publisher=Harvard University Press|year=2011|isbn=9780674063693|pages=197}}</ref> Household heavy cavalry ([[knight]]s) became common in the 11th century across Europe, and [[Tournament (medieval)|tournaments]] were invented. Tournaments allowed knights to establish their family name while being able to gather vast wealth and renown through victories. In the 12th century, the [[Cluny]] monks promoted ethical warfare and inspired the formation of [[order of chivalry|orders of chivalry]], such as the [[Knights Templar|Templar Knights]]. Inherited titles of nobility were established during this period. In 13th-century Germany, knighthood became another [[inheritance|inheritable]] title, although one of the less prestigious, and the trend spread to other countries.
