In the course of the 12th century knighthood became a social rank, with a distinction being made between "milites gregarii" (non-noble cavalrymen) and "milites nobiles" (true knights). As the term "knight" became increasingly confined to denoting a social rank, the military role of fully armoured cavalryman gained a separate term, "man-at-arms". Although any medieval knight going to war would automatically serve as a man-at-arms, not all men-at-arms were knights. The first military orders of knighthood were the Knights of the Holy Sepulchre and the Knights Hospitaller, both founded shortly after the First Crusade of 1099, followed by the Order of Saint Lazarus (1100), Knights Templars (1118) and the Teutonic Knights (1190). At the time of their foundation, these were intended as monastic orders, whose members would act as simple soldiers protecting pilgrims. It was only over the following century, with the successful conquest of the Holy Land and the rise of the crusader states, that these orders became powerful and prestigious.
