In the year of the thousandth anniversary of the first Polish royal rituals of 1025, it is worth reconsidering the question of papal approval of royal coronations during the Piasts' inauguration rites in the 11th century. This paper re-examines the role of the papacy in legitimising monarchs in the early and high Middle Ages, examining legal, theological, and political aspects. Analysing sources and historiography, it explores how rulers dealt with papal approval and its regional variability. This study reassesses the papal role in coronations, offering new insights into medieval power dynamics, especially in medieval Poland.
