The purpose of the study is to develop a model of human-centered adaptive constitutionalism through a detailed analysis of the historical and legal evolution of constitutional ideas concerning the human person. The research strategy integrates historical-legal, comparative-legal, systemic, and structural-functional approaches into a unified and comprehensive methodological framework. The documentary and normative source base comprises international legal instruments, documents of the United Nations, the Council of Europe and the European Union, and national legislation. The chronological scope of this comprehensive analysis extends over the period from the formation of classical constitutionalism in the eighteenth century through regulatory acts and doctrinal developments published between 2024 and 2026. The method of legal modeling was used to build the authors’ concept; a forward-looking analytical approach was employed to assess the emerging trends in the further development of constitutionalism. The analysis finds that the normative focus of constitutional legitimacy is gradually shifting from the state toward the human person, individual rights, and human dignity. A comparative analysis of classical, social, global and digital constitutionalism has shown differences not only in the substantive protection and implementation of fundamental human rights, but also in the institutional and legal mechanisms for guaranteeing those rights. Traditional models were focused on limiting state power, while modern approaches increasingly seek to regulate digital platforms, algorithmic systems and transnational entities. The research demonstrates that significant risks to human rights arise not only within the field of traditional public administration, but also in the digital environment. A detailed structural architecture of human-centered adaptive constitutionalism is proposed, encompassing five closely interconnected dimensions of individual rights protection: constitutional, international, digital, algorithmic, and institutional monitoring mechanisms. The scientific novelty of the study lies in the combination of historical-legal, international-legal and digital-technological aspects within a single conceptual model. The findings and proposed conceptual framework may be used by legislators, constitutional review bodies, ombudsmen, and international institutions.
