Final answer:
Courtly love in the Medieval Era served as a model for the chivalric code rather than affecting marriage practices. It was an idealized form of romantic expression among the nobility, promoting knightly virtues and platonic ideals associated with the feudal system's social hierarchy.
Step-by-step explanation:
Courtly love provided a model for the chivalric code in the Medieval Era. It was a set of ideas about love that included chivalry, a noble and respectful approach to love and courtship, expected of knights and noble men. The concept of courtly love was originally a literary genre that entertained the nobility but spread across Europe, influencing the social behaviors of the higher classes.
The notion of courtly love was usually dedicatedly platonic and linked to brave deeds done for fair ladies, recounted in literature, poetry, and songs of troubadours, often associated with the popularized court of King Arthur. It was not about arranged marriages, marriages based on love, or directly related to slavery and servitude, but rather about idealizing and Christianizing knightly behavior and conduct within upper-class romantic contexts.
Europe's feudal society relied on a system of social obligations and ties. Courtly love played into this system by reinforcing the social hierarchy and providing a moral compass for the noble warriors within their social and military roles as vassals and protectors. It depicted an ideal of nobility and romantic aspiration that was in stark contrast to the utilitarian approach to marriage and relationships prevalent among the lower classes and even within the nobility for practical purposes such as alliances and economic considerations.
