Dynamics of Changes in the Structure of Intersystem Legal Entities in the XIX Century
The article examines the stages of structural change of intersystem legal entities created by states in the 19<sup>th</sup> century in order to regulate various types of cross-border social relations. Purpose: to determine the general dynamics of the formation and development of the structure of intersystem entities in the practice of states in the 19<sup>th</sup> century and stress the features of each of its stages. The methodological basis of the study was composed of general scientific and special methods of enquiry, including the historical method, methods of formal logic, analysis, synthesis, as well as the systemic, comparative legal and interpretation methods. Since the 19<sup>th</sup> century to regulate certain types of cross-border social relations states have been forming intersystem entities based on their own national law. In content, such entities are individual, but in the process of the formation of their structural elements it's permissible, somewhat conventionally, to single out several common stages of their formation and development. During the research three basic stages of the structural change of such entities in the 19<sup>th</sup> century were pointed out. Initially, foreign law was allowed to regulate cross-border relations. Then the states begin the process of mutually elaborating unified approaches to the regulation of the corresponding cross-border relations, and the respective intersystem entities receive a legal component. At the next stage, international legal acts appear aimed at regulating cross-border social relations but developed and adopted by new subjects of international law - international intergovernmental organizations.
