Abstract
The article notes that the sources of legitimacy were different in ancient and medieval times than today. It is emphasized that the concept of legitimacy in China emerged from a complex interplay of philosophical ideas, cultural beliefs, and historical precedents. The Mandate of Heaven, Confucianism, and legalism each provided different sources through which rulers sought to legitimize their authority. In ancient Greece, the concept of legitimacy arose from a combination of civic participation, philosophical thoughts, mythological narratives, and the pursuit of virtue. In ancient India, however, the concept of legitimacy was deeply rooted in the rich tapestry of spiritual, social and philosophical ideals. Dharma served as a spiritual compass that guided rulers to maintain cosmic order and ethical principles. The article also notes that the sources of legitimacy in ancient Rome were multifaceted, based on a combination of mythology, legal foundations, religious symbolism, and the ability to ensure stability and prosperity. In medieval Europe, the concept of legitimacy was shaped by the complex dynamics of feudal relations, religious beliefs, and evolving political structures. In medieval Islam, the concept of legitimacy was deeply rooted in the caliphate, the implementation of the Sharia and the pledge of allegiance. The interaction of political and religious factors determined the sources of legitimacy, emphasizing the importance of rulers to rule according to Islamic principles. The scientific result of the article, the novelty and importance of the work is that it shows how the concept of legitimacy changes over time and space and the impact of these changes on the management structure of societies. The author emphasizes that the sources of legitimacy in ancient and medieval times, unlike in the modern era, originated more from religious, philosophical and cultural contexts. The novelty of the work is the comparative presentation of specific models of legitimacy in ancient China, Greece, India and Rome, as well as in medieval Europe and the Islamic world. The main hypothesis is that the sources of legitimacy were formed according to the social, economic and ideological realities of the time and had a direct impact on the management mechanisms. The importance of the work is that it provides an opportunity to better understand the dynamics of legitimacy in the modern era and build effective governance structures by learning from its historical models. This approach creates a new perspective for both philosophical and political-legal studies.
