EMER DE VATTEL’S INPUT INTO DEVELOPMENT OF INTERNATIONAL LAW Didmanidze Ulan Temurovich, postgraduate student. <...> The theoretical legacy of E. de Vattel on the sovereignty, national interest and the country as a whole had an impact on the ideology of the French Revolution. <...> Vattel gave a precise and very typical definition of state sovereignty, and the traits that he has given this concept absent from the political philosophy of the famous French philosopher Jean Bodin. <...> Philosophy E. de Vattel was deeply rooted in the ideology of the Enlightenment, which is intellectually prepared the ground for the French Revolution of 1789-1794. <...> With this understanding of international law came to be regarded as a coherent concept, which coincides with the will of the state, and not as a godsend gift. <...> To achieve this goal within the framework of preparation of this article has been applied general scientific methodological approach that allows to determine the scope of the study, to clarify the basic concepts and categories related to the history of international law, to identify the key conceptual aspects of the research topic. <...> The study used scientific methods of cognition, such as analysis and synthesis, generalization, dialectical. <...> Widely used special methods of science: comparative law, legal and technical. <...> E. de Vattel has made a contribution, primarily in support of the idea of gaining full sovereignty of States. <...> Although he called himself a supporter of the theory of natural law, his works E. de Vattel paved the way for legal positivism. <...> E. de Vattel shared the views of H. Grotius as to what controls the affairs of human right given from above (ie, "higher law"), not a right created by the people themselves. <...> E. de Vattel raised the role of the state and the state will at such a height that legal positivism - theory according to which the right is formed from the positive actions of the states - was the natural result of the expressed E. de Vattel ideology. <...> Among his achievements is the fact that he has developed in more detail the question of methods of resolution of interstate disputes without resorting to war. <...> This, of course, it was important to consider the issues related to the violation of international obligations of States, but little is added to G. Grotius developed the provisions of the use of war to resolve disputes and the methods of warfare <...>
