This study starts from the institutional aspect and analyzes how federalism, as a compound structure, divides power between the central and local governments. Then, this study mentions that federalism also has its normative connotations, which are traceable to the theological concept of a covenant. We also elaborate on how the success of the United States’ federalism strengthened its institutional aspect while overshadowing the older covenant tradition. Next, this study presents a typological framework of federalism, introducing concepts such as coming-together federalism and holding-together federalism; dual federalism and cooperative federalism; decentralization and non-centralization; and asymmetrical federalism, non-territorial autonomy, and consociationalism, presidential and parliamentary federalism, as well as democratic federalism and authoritarian federalism/facade federalism. Next, this study compares monist federalism with multinational federalism. Then, this study examines the specific applications of federalism in fiscal, environmental, health-care, and social-welfare policies. By reviewing the history, theoretical origins, institutional development, and contemporary manifestations of federalism, this study provides a roadmap for scholars in the field of federal studies. Finally, this study also puts forward several testable hypotheses, aiming to provide operational research agendas for future studies. © 2025 by the author.eninfo:eu-repo/semantics/openAccessAutonomyFederalismInstitutionNormativeArticle10.3390/encyclopedia50401562-s2.0-105025975613
