In particular France and England, where if I am not mistaken, the crown considered themselves partially divine in nature. There is also the close relationship between the french crown and the Avignon papacy.
I'm not particularly knowledgable on the subject, but I just feel obligated to state that the idea of apotheosis, or the divine right to rule, did not live in most European monarchies until the rise of Protestantism (though it spread through most of Europe regardless of religion). The idea came to be in an attempt to unify the previously separate institutions of church and state. The divine right of kings is, in fact, one of the defining aspects of Europe's absloute monarchies period. Thus, any representation of a medieval European ruler styling him/herself and being held by most of his/her subjects as one with a divine right to occupy the throne is exaggerated at best.
