What Does Chivalry Mean?

The word chivalry describes a kind of behaviour that is very polite and it shows the sense of honour that you have towards somebody. Though the word can be used for anybody but seldom will you find its use when describing a polite behaviour of a man towards another man; it describes the polite behavior of a man towards a woman.
     
But its use changes in different contexts and many people have interpreted its use as they please. When you are in the US state of Texas its meaning they say is that it's a man's privilege to decide what kind of behavior he intended towards a woman.
             
In historical context the word was used in the Middle Ages in the context of religious and moral system of behaviour which every knight was expected to follow.
