Final answer:
Key chivalrous traditions among knights included a code of conduct upholding the church's values and the practice of courtly love, both shaping knightly behavior and the culture of European nobility.
Step-by-step explanation:
Two important chivalrous traditions among knights are the adherence to a code of conduct reflecting the church's values and the ethos of courtly love. These traditions stem from the medieval desire to Christianize knightly behavior, ensuring that knights not only embodied the prowess and skill expected of them in battle but also espoused the virtues of loyalty, honor, and the protection of those who could not defend themselves, such as women and the clergy. Additionally, knights engaged in courtly love, which elevated the status of women within aristocratic culture and focused on nobility, manners, and the art of love as expressed through poetry and song by troubadours.
The ethos of chivalry emphasized that knights should protect the church, women, and the defenseless, and observe sacred truces and holy days without engaging in combat. Courtly love was a culture of amorous relationship expressed in vernacular languages, embodied in stories and songs about knights and their ladies, which greatly influenced European noble culture.
