From the old French word for knighthood, "chevalerie", the art of being a chevalier (a knight or horseman).
This was originally a system by which mounted warriors were to act, but while service to their people is touched upon the general goal of medieval knights was not saving many a damsel in distress, devotion to God, or enforcing justice; most knights defined chivalry as warfare and obtaining fame and fortune in the name of their king(s) and without any display of cowardice in battle. In a sense, it's hardly different from joining the military for the benefits that it offers, including the money that pours in from the business of war. Chivalry was basically a boy's culture: fighting other men, riding horses, power and profit and the ability to exploit that power.
The modern notion of chivalry as courtesy to women has tenuous links to chivalry as it was originally conceived. Perhaps courtly love (coined in 1883 to describe the worship of a married noblewoman by a lowly troubadour or knight and his vow to do great deeds in her honor) influenced this notion, but courtly love is, for all intents and purposes, adultery (very dangerous to both participants) and to what extent that courtly love was ever practiced remains unknown.

Something women complain is dead even though it cannot logically exist in an equal society, which is something women wanted. It's one or the other.

Chivalry is when a guy does something nice for a woman that is not usually expected in modern times. The consists of a guy just doing the gentlemanly thing.

Something that people always say is dead, but no one seams to know what the hell died..
