Right to rule is such a common phrase and concept that it could fit for anyone: divine right, constitutional monarchies, parliaments, elective monarchies, god kings...Does "Right to Rule" fit modern England?
But I personally think that countries that changed in that regard from one age to the next are good candidates, i.e., for Europe: Britain or the Netherlands in the modern age; the HRE or Poland in the exploration age. But the pack could just as well include Edo Japan and Assyria and be thematic with the title.
