In this article, we purpose to catch the historic significance and character of the new chivalry which is described as the ideal type of middle age through the De laude novae miltiae written by St. Bernard. As the excellent witness of the second crusade and serious historian in narrating about the clerical and warrior world, St. Bernard preaches not only the inevitability but also the legitimacy of crusade. Besides, he is charged with granting the ideal and value of the new chivalry in the XIth and XIIth centuries for the sake of realizing the justice of God.
The De laude novae miltiae is composed by two parts(I, 1-V, 10 and V, 11-XIII, 30); one is devoted to justify the monks-chivalry, what is called, who show the ideal type of new chivalry and the other is dedicated to explain the holy land including Jerusalem by the biblical analyse. St. Bernard presents a new model of chivalry that is competent for accomplishing the battle against pagans, like a professional, in getting under arms. Most of all, It is certain that the new chivalry must protect the church and weak. In addition, the brave chivalry must fight against infidels for the glory of God. In a word, St. Bernard tries to recreate the new chivalry in pursuing the religious itinerary and the practical principes. Briefly described, St. Bernard takes an important place of the apostle holding responsible for the new chivalry through the De laude novae miltiae. It is possible to speak that the new chivalry means the ideal type in the christian world for him.
