This study analyses military laws determined by Mkhitar Gosh, Smbat the Constable, Nerses Shnorhali, Nerses of Lambron, and Shahamir Shahamiryan. Their legislative activity tends towards realising goals of Armenian sovereignty, national security, human rights, and national interests. Military laws establish the order of military service, types of military troops, the rights and obligations of military personnel, issues of war and peace, regulations of captivity, and the protection of individual and property rights of peaceful civilians. The codes contain a number of criminal and legal norms which condemn the violation of laws by military personnel, and the corresponding punishments determined for such transgressions. Armenian legislators highlight not only the capacities of various military rank, but also their human qualities.They call for avoiding violence not only against Armenians, but also against peaceful populations and hostages of occupied territories. Military laws have contributed to the reinforcement of the Armenian army, the strengthening of the sovereignty of the Armenian state, the defense of national security, the establishment of domestic order, and the expansion of moral education.
