International law is defined as the legal entity that regulates the relationship between subjects of international law in the most basic sense. Who are these subject of international law? According to the general view accepted in doctrine, subjects of international law are mainly composed of mainly states and international organizations, sui generis communities, and individuals which are related to international law to the extent that. International law constitutes a part of the discipline of international relations on the basis of international law which regulates the relations among its subjects. Therefore, in order to better understand the norms of international law, it is necessary to have knowledge about the basic theories of international relations. One of the fundamental shortcomings of the academic community that deals with the disciplines of international law and international relations is that they can not fully understand the interrelationship of these two connected disciplines by dealing only with their own disciplines. We will try to resolve this lack of hope in our academic work that we hope to be able to bring forth new ideas on an international scale that will be useful for international law, and we will try to walk on this path. In addition to this, it will try to be beneficial to the students with the course notes published from time to time.
