The monograph examines the nature of the modern state, formulates the priority agenda of state research for political science in the context of the formation of new political spaces. The authors analyze the transformation of the national state in the context of global instability and current trends in the development of statehood in the countries of the European Union and in the post-Soviet space. Alternatives to reformatting the state in the context of ongoing shifts in the world order, in the political landscape and social structure of society, in the values ​ ​ and guidelines of human identity of the 21st century have been identified. Predictive assessments of changes in the political and managerial functions of the state are justified, taking into account the complication of modern social reality and the emergence of new challenges to security and development.
