The idea of imperial monarchy emphasised the dignity of the crown and included its role as a unifying national force, defending national borders and interest, royal supremacy over the law and a distinctive national church within the Catholic communion. James V was the first Scottish monarch to wear the closed imperial crown, in place of the open circlet of medieval kings, suggesting a claim to absolute authority within the kingdom. His diadem was reworked to include arches in 1532, which were re-added when it was reconstructed in 1540 in what remains the Crown of Scotland. During her brief personal rule Mary, Queen of Scots brought many of the elaborate court activities that she had grown up with at the French court, with balls, masques and celebrations, designed to illustrate the resurgence of the monarchy and to facilitate national unity. However, her personal reign ended in civil war, deposition, imprisonment and execution in England. Her infant son James VI was crowned King of Scots in 1567.
