Chivalry is an essential part of the world of Parzival. The chivalric code is a loose, informal system of etiquette that governs behavior in the literary world of medieval Europe (See: Background). To be a knight is to adhere to the code, which dictates how and why people should behave. For the aspiring knights in Parzival, understanding of, and adherence to, the code is essential, and its primary importance is emphasized throughout the story.

Parzival and Gawan want to prove their worth as men, as knights, and as potential members of the Table Round. As such, they strive to live by the code of chivalry at all times. The code demands a devotion to God, it governs the rules of battles and duels, and—most importantly—it establishes the importance of honor in courtly society. A knight’s honor is very important and, if a knight wishes to preserve or add to their good reputation, they must act in an honorable fashion, as dictated by the code. As such, the characters in Parzival do not only want to adhere to the code. They want to embody it: They protect the weak, offer their services to lords, fight for God, and duel against anyone who might besmirch their honor.
