First orders of chivalry appeared in Serbia during the reign of Stefan Nemanja, in the 12th century. As the protector of the dynasty was Saint George, the main order was named after him. Hungarian Order of the Dragon spread over to Serbia in the 15th century. Despot Stefan Lazarević belonged to the highest order, while several other noblemen were members of the order's lower ranks. At first, all members of the orders of the knights were members of nobility. Young men were not only trained for physical and warrior skills, but were also taught philosophy, foreign languages or court etiquette. The most popular role models were heroes from the Antiquity, especially Alexander the Great. After coming of age, young nobles were settling in their patrimonies and "pronoias", awaiting calls from their lords. The initiation into the order was usually conducted on the battlefield, either before or after the battle. First Serbian king who hired foreign mercenaries, as he couldn't mobilize enough domestic warriors, was King Milutin. They formed a special estate of the realm. Emperor Dušan also had a personal, foreign-based guard.
