Courtly love was a medieval European literary conception of love that emphasized nobility and chivalry. Medieval literature is filled with examples of knights setting out on adventures and performing various deeds or services for ladies because of their "courtly love". This kind of love was originally a literary fiction created for the entertainment of the nobility, but as time passed, these ideas about love spread to popular culture and attracted a larger literate audience. In the high Middle Ages, a "game of love" developed around these ideas as a set of social practices. "Loving nobly" was considered to be an enriching and improving practice.
