The authors investigated the mechanism of interconnection of ideas of global constitutionalism as a social concept with socia reality, denoting the socio-historica conditions of its origin and development. The article proves that emergence and development of the social concept of global constitutionalism is due to a set of socio-economic, sociopolitical, historical and legal conditions that, in their interrelation and interdependence, determined the main features of this social concept, as well as the forms and stages of its implementation in the social reality of national societies and states as well as internationally. These conditions for the emergence and development of the socia concept of global constitutionalism can be classified into a number of stages: the stage of the formation of the socia concept of global constitutionaism, the definition of its system-forming features and the formulation of global democratic values; the stage of creating nternational and supranational political and legal institutions acting as unified control centres of regulation and contro, which consists in the forcible export of values of constitutional democracy on a planetary scale.
