The authors discuss key factors necessary to determine power’s legitimacy and meticulously elaborate on the pertinent dimensions encompassing it. The article focuses on the factors that threaten the maintenance of unchallenged power, specifically the spectre of illegitimacy, and those that reinforce its consolidation. By concentrating exclusively on two key pillars – dimensions and categories – the article aims to establish a theoretical framework for investigating the legitimisation of political authority. This endeavour is crucial in comprehending the intricate interplay between society and power. It also has a clear research objective, i.e. to identify the specific area, scope, and pivotal junctures in the legitimisation process where dimensions and categories exert their most profound and immediate impact. Consequently, the reader gains a thorough understanding of the complex and diverse processes involved in legitimisation, encompassing legal, political, and societal dynamics.
