Why do knights wear a helmet?

Knights wear helmets primarily for protection, safeguarding their heads during combat from weapons and projectiles. Helmets were designed to absorb and deflect blows, reducing the risk of serious injury or death. Additionally, helmets often featured visors to protect the face while allowing knights to see and breathe, enhancing their effectiveness in battle. Overall, the helmet was a crucial component of a knight's armor, combining functionality with the symbolism of their status and role.
