Training to become a knight began at age 8 when boys were sent to live at neighboring castles. They were taught skills like horseback riding and fighting with weapons. At 15 or 16, they became squires and assisted knights by caring for their armor and horses. At around age 20, squires could undergo a dubbing ceremony to become knights if a lord deemed them worthy. This involved rituals like fasting and being tapped on the shoulders with a sword. Men could also become knights for displaying valor in combat.
