The article is devoted to the study of images of Royal power that were used by the last Valois dynasty’s representatives, reflecting the transformations that occurred in connection with the attempt to strengthen the Royal authority with intensification of secular power and gaining spiritual power. Studying the French Royal medals of the end of the XVI century, it is possible to identify the main trends of changes in the image of the Royal power during the development of religious conflict, demonstrating the increasing role of certain Christian symbols that were used both to indicate their religious position and its presentation to society during the state crisis. The study analyzes the medals of the time of Charles IX, in particular in memory of St. Bartholomew’s night, and the medals of Henry III. Analysis of these images allows us to come to the conclusion about the evolution of ideas about the king and his power from the image of the ancient hero king that was formed at the time of the beginning of religious wars, to the restoration of the idea of the most Christian king and peacemaker king, common in the pre-Renaissance era, and which is most clearly shown in the images of Henry III.
