The education focused on both moral virtues and physical skills needed for combat. They were often sent to serve in the households of veteran warriors or noble families, learning the ways of knighthood and gaining experience.
This early training was typical across different cultures and times, including during the period of the Crusades when knights and soldiers from all walks of life joined the movement, motivated by religious zeal, the promise of land, and adventure.
