Here is a question about this article: Parallel to the military developments emerged also a constantly more elaborate chivalric code of conduct for the warrior class. This new-found ethos can be seen as a response to the diminishing military role of the aristocracy, and gradually it became almost entirely detached from its military origin. The spirit of chivalry was given expression through the new (secular) type of chivalric orders; the first of these was the Order of St. George, founded by Charles I of Hungary in 1325, while the best known was probably the English Order of the Garter, founded by Edward III in 1348.
What is the answer to this question: In what year was the Order of St. George founded?
