France’s monarchy, and especially its religious dimensions, has long fascinated historians. In analysing how the new Bourbon dynasty attempted to entrench its right to rule from the 1590s onwards, Sean Heath focusses on how it promoted and expanded the cult of Louis IX (Saint Louis after 1625). Drawing on an unusually wide range of sources, from music to academic orations, he offers a new account of monarchical legitimacy in the making, whose ultimate beneficiary and image was Louis XIV. A book that will enlarge our view of absolute monarchy in the making.
