 ::In Monaco, she is accorded the title and style of HRH The Princess of Hanover (SAR la Princesse de Hanovre). That is the valid title. Even in Germany, a republic, she is accorded the style of HRH and the title of Princess of Hanover only because it is recognized in Monaco. The difference is that HRH's husband *may* not be so recognized. There are plenty of other articles that utilize defunct titles and styles, however, those stay. For instance, check out the Luxembourgish Grand Ducal Family. They all use HRH when that HRH (of Parma) ""isn't valid"" anymore and may not have been in the first place. Nonetheless, the sovereign of Luxembourg recognizes it as do foreign governments. The same holds true for Caroline. Her father, and now her brother, recognize her as HRH The Princess of Hanover. If you insist, edit every single article on German royals after 1918. I can guarantee that your ideology will have you blocked. That's not a threat from me, that's just careful guesswork.  "
