Once more, the question was about “reigning royal families”. AFAIK, the GM does not belong to any reigning royal family. You said it is included in the GHdA. I did not say the opposite. But it is not listed in the section I of the Almanach de Gotha. The prestige and authority of the latter cannot be compared to the former.
So, the answer to Pedro’s question is “no”. No European royal family recognise the rights of the Borbon-Segovia line or consider them to be royal. Maybe with the exception of Monaco in recent times.
If you have sources or information to affirm the opposite, please share it with us.
No reigning royal house has recognised the Borbon-Segovia line’s pretension to the French throne.
In 2000 Louis de Bourbon was made a Bailiff Grand Cross of Honour and Devotion of the Sovereign Military Order of Malta with the style "duc d'Anjou" by a reigning prince, the Prince and Grand Master of the Order of Malta. In 2016 his wife was made a Dame Grand Cross of Honour and Devotion (a rank to which she could claim no right by her birth and ancestry, but only on account of her marriage to the head of a royal house).
Has any reigning prince similarly honoured prince Jean d'Orléans - either with or without an Orléanist title?
The question was about royal families or royal Houses. I know about the order of Malta. There are no dynastic rights in the order. The Grand Master is elected. Not a hereditary monarchy. Not sure if it can be considered a monarch. Contrary to the Pope, the Grand Master is not listed in the first section of the Almanch de Gotha.
The Sovereign Military Order of Malta is listed in the first section (1. Abteilung) of the Genealogisches Handbuch des Adels, Fürstlichen Hauser - albeit after the letter Z. In the table of contents, that is clearly part of 1. Abteilung. The Order was most recently included in Band XIX, 2011.
A prince can reign. A royal house is only said to be reigning because the head of that house reigns. Those who don't think that the Prince and Grand Master of the Sovereign Military Order of Malta is "reigning" can argue that point with the 108 nations which maintain diplomatic relations with the Order.
