About Royal Institutions, Titles and Hierarchy in the 7 European Kingdoms

[0325.Mikael.0929]

Sweden:
The Institutions:

• "Sveriges Kungahus" = "Swedish Royal Court"
  • The organisation that supports the Head of State and the Royal Family
• "Det Kungl. Huset" = "The Royal House"
• "Den Kungl. Familjen" = "The Royal Family"

The Hierarchy and Titles:

1. The King/Queen Regnant and the Queen Consort/Prince Consort
   • The Head of State and his/her spouse
   • Title: HM King, HM Queen, HRH Prince (Prince Consort)
     (e.g. Frederik I is known as HRH Prince Frederik of Sweden before 1720)
2. The Crown Prince/Princess
   • The first in line to the Swedish throne who is also an heir apparent, and his/her spouse
     (e.g. Crown Princess Victoria) (Prince Bertil was first in line in 1973, but was never a Crown Prince)
   • Title: HRH Crown Princess, HRH Crown Prince
     (not used by spouses of the heiress apparent, e.g. Prince Daniel is not known as the Crown Prince)
3. The heir to the apparent to the heir apparent and his/her heir, etc. and their spouses
   • Those whose position in line to the throne cannot be displaced and their spouses
     (e.g. Prince Gustaf Adolf and Princess Estelle)
   • Title: HRH Prince, HRH Princess
4. The siblings (born after 1977) / brothers (born before 1977) of Groups 1-3 members, and their spouses
   (e.g. Prince Carl Philip, Princess Sofia, Princess Madeleine and Prince Oscar)
   • Title: HRH Prince, HRH Princess
5. The sisters of Groups 1-3 members born before 1977 who were either married with governmental consent or unmarried
   (e.g. Married: Princess Birgitta, Princess Ingrid / Unmarried: Princess Eugenie)
   • Title: HRH Princess
6. The children of Group 4 members
   (e.g. Prince Lennart before 1932, Princess Leonore, Prince Alexander)
   • Title: Prince, Princess (had HRH title before 2019)
7. The sisters of Groups 1-3 members born before 1977 who did not marry with governmental consent
   (e.g. Princess Margaretha, Princess Desirée, Princess Christina)
   • Title: Princess, (female variant of spouse's title)
8. The brothers of Groups 1-3 members born before 1977 who did not marry with governmental consent
   (e.g. Oscar, Carl, Sigvard, Lennart, Carl Johan)
   • Title: Count of Wisborg / Prince Bernadotte (not granted by Sweden)
9. All others
   (e.g. Baudouin of Belgium, Harald V of Norway, Charles Edward Ambler, Carl Gustaf Victor Magnuson, Folke Bernadotte)
   • No Swedish titles

Groups 1-5 constitute the Royal House, Groups 1-4 and 6 has succession rights while Groups 1-8 constitute the Royal Family, provided that they are Swedish citizens. (Hence Christopher O'Neill, despite being the spouse of Princess Madeleine, is NEITHER a Prince of Sweden, NOR the Duke of Hälsingland and Gästrikland)

Out of curiosity, is there a reason you included all of the kingdoms in Europe excepting Norway?

Probably because the Norwegian nobility was legally abolished in 1821.

But Mbruno's summary covers royal titles and styles, and the Norwegian monarchy was never abolished. (He covered noble titles in a separate document here: https://www.theroyalforums.com/foru...lity-and-aristocracy-31460-4.html#post2383536)

Actually, in that other post, I was going to mention in the Denmark/Sweden sectiion that the Norwegian nobility had been abolished, but I got lazy of writing too much and didn't do it.

To be honest, I don't know much about Norway either, so I usually refrain from commenting on Norwegian topics.

Thank you for the summary! It is worth mentioning that HH is only meant to be used outside of Norway. For that reason, it is not used on the Norwegian version of kongehuset.no.

will Sverre Magnus become Crown Prince before I-A gives birth to her child?)

Are you referring to a scenario in which the still-childless Ingrid Alexandra is Crown Princess or a scenario in which she is Queen?

In the first scenario I would think it highly unlikely, as neither Princess Märtha Louise nor Princess Ragnhild were Crown Princess while their respective brothers were childless Crown Princes.

In the second scenario I think it would be possible, as he would be the heir to the throne, and many European countries have extended the traditional titles of the monarch's eldest son to the heir or heiress to the throne irrespective of their relationship to the monarch.

I assumed the latter. There are also examples that did not confer the traditional title. Belgium didn't confer the title 'Duke of Brabant' on Prince Albert (who was the Prince of Liege) when his brother was king; as this title is reserved for the oldest son (now child) of the king.

Are there any Scandinavian examples of the title of Crown prince(ss) being held by a sibling of the monarch? Knud for example was never the 'Crown prince' - but was known as 'Hereditary Prince' (I don't think it was an official title but please correct me if I'm wrong) when first in line to the throne. In Sweden, Bertil was never the Crown prince while being first in line to the throne from the day his nephew became king until the king's son was born.

So, to me, it doesn't seem likely. Especially not while Queen I-A would still be of childbearing age; they might create a title like 'Hereditary Prince' instead?!

My understanding is that the term "Crown Prince" in Scandinavia applies to the heir apparent to the throne whereas "Hereditary Prince" in Knud's case was a title that applied to a male heir presumptive.

In Sweden, Carl Gustaf for example became Crown Prince when his grandfather ascended the throne because, even though he was not a son of the King, he was at that time the heir apparent (as he had outlived his father).


In summary, as I understand it:


1. Prince of Asturias: heir presumptive, male or female, automatic.


2. Prince of Orange: heir presumptive, male or female, automatic.


3. Crown Prince (Scandinavia): heir apparent only, previously male only, automatic.


4. Prince of Wales: heir apparent only, male only, must be granted separately.
.

5. Duke of Brabant: eldest child of the King, automatic; if the Duke of Brabant has issue and the King outlives the Duke of Brabant, the title passes automatically to the Duke's eldest child.

 

[Tatiana Maria]

Are there any Scandinavian examples of the title of Crown prince(ss) being held by a sibling of the monarch?

Yes in Denmark (for sisters of future monarchs). Christian VI introduced the rule that the eldest daughter of the King enjoyed the title of Crown Princess unless and until she, or the eldest son of the King (the Crown Prince), was married. (Historians of today normally call them Princesses, but the titles are always written in 17th and 18th century publications.)

This rule appears to have been repealed by Frederik IX, since his daughter Margrethe (the present Queen) was not styled Crown Princess when her father ascended the throne.

In Sweden, Bertil was never the Crown prince while being first in line to the throne from the day his nephew became king until the king's son was born.

So, to me, it doesn't seem likely.

But as I said, other European monarchies have altered the same rule, and of those, some are more wed to tradition than the Norwegian monarchy.

whereas "Hereditary Prince" in Knud's case was a title that applied to a male heir presumptive.

Knud for example was never the 'Crown prince' - but was known as 'Hereditary Prince' (I don't think it was an official title but please correct me if I'm wrong) when first in line to the throne.

Knud was known as Prince Knud when he was first in line to the throne. When he lost his position to his niece Margrethe he was conferred with the title of Hereditary Prince.

Thank you for the correction. Was Knud ever given the title of Tronfølgeren as Margrethe was ?


Traditionally, I still think Arveprins was the title of a male heir presumptive. I wonder why the title was not given to Knud in 1947-1953.

 

[Tatiana Maria]

Thank you for the correction. Was Knud ever given the title of Tronfølgeren as Margrethe was ?

Yes, he was; I understand that to be what the article is referencing regarding his officially becoming "Heir to the Throne".


Adding onto my previous post, the rules conferring the traditional titles on heirs presumptive were modified for Spain in 1987 (although the Spanish rules had been modified at various times before), for the Netherlands and Monaco in 2002, and for Luxembourg in 2012. The examples of Albert of Belgium, Knud of Denmark and Bertil of Sweden all predate this trend.

But an heir presumptive still cannot be Duke of Brabant and, apparently, the rules have not been changed yet in Denmark and Sweden either (or at least we won't know that until a new concrete case arises).

 

[Tatiana Maria]

Traditionally, I still think Arveprins was the title of a male heir presumptive. I wonder why the title was not given to Knud in 1947-1953.

I'm not sure, but the tradition was not treated as automatic. Hereditary Prince was not given to Christian Frederik in 1808-1839 or to Christian in 1863.

King Frederik IX, as I mentioned above, breached tradition in denying his unmarried daughter the title of Crown Princess when he ascended the throne, so perhaps he was a minimalist.

But an heir presumptive still cannot be Duke of Brabant and, apparently, the rules have not been changed yet in Denmark and Sweden either (or at least we won't know that until a new concrete case arises).

Yes, my understanding is that there are no official rules set out in the Scandinavian monarchies, as least as far as we know. Out of the European monarchies with official rules governing crown princely titles, four have made them automatic for any presumptive heir (Spain, the Netherlands, Luxembourg, and Monaco), two have made them automatic for heirs apparent who are children or grandchildren to the monarch (Belgium and Liechtenstein), and one has not made its primary title automatic for any heir (the United Kingdom).

King Frederik IX, as I mentioned above, breached tradition in denying his unmarried daughter the title of Crown Princess when he ascended the throne, so perhaps he was a minimalist.

When he ascended the Throne Margrethe was not even in line of succession. He only could have given her the Title Crown Princess after the change of the succession law in 1953.

 

[Muhler]

It's really quite simple:
The Crown Prince = Always the oldest living (unless bypassed for physical or mental reasons) child of the monarch.
The Successor (Tronfølger) = A child of the monarch who is the official heir under the condition that XYZ doesn't happen.
The Hereditary Prince (Arveprins) = The next in line from another branch of the family. In case the monarch is childless or the children have malfunctioned.

In DK the title of Crown Prince/ss is automatically given to the oldest living child of the monarch. - That is ensured in the Constitution, because the Crown Prince has a specific constitutional role.
But The Heir (Arvingen) or The Successor (Tronfølgeren) are also unofficial titles for the Crown Prince, so constitutionally speaking these titles makes no difference.
Just as the unofficial titles of The Monarch, The Majesty or The Regent are sometimes used for the King/Queen.

So in the case of Norway. Magnus may be Arveprins Magnus (Hereditary Prince) when it is assumed or determined that queen Ingrid is unlikely to have children of her own. Say when she's around 45.
He will not become crown prince, because he is not a child of Ingrid, and because she might theoretically have a child.
But Norway basically being a hereditary republic, I think it's likely that Magnus will simply keep his title as Prince, and become king when Ingrid dies, childless. He will perform the same functions as a crown prince or hereditary heir, just without the title.

 

[Tatiana Maria]

Yes in Denmark (for sisters of future monarchs). Christian VI introduced the rule that the eldest daughter of the King enjoyed the title of Crown Princess unless and until she, or the eldest son of the King (the Crown Prince), was married. (Historians of today normally call them Princesses, but the titles are always written in 17th and 18th century publications.)

This rule appears to have been repealed by Frederik IX, since his daughter Margrethe (the present Queen) was not styled Crown Princess when her father ascended the throne.

When he ascended the Throne Margrethe was not even in line of succession. He only could have given her the Title Crown Princess after the change of the succession law in 1953.

When they received the title of Crown Princess, none of the eldest daughters who carried the title were in the direct line of succession, since Denmark used semi-Salic succession from 1665-1853. Only if there were no males in paternal line available could the Crown Princess, or any other Princess, ascend the throne.

For that reason, I don't think Margrethe's exclusion from the succession was the reason for the change of tradition. And had it been the (only) reason, she would have received it when she was given succession rights in 1953.

In DK the title of Crown Prince/ss is automatically given to the oldest living child of the monarch. - That is ensured in the Constitution, because the Crown Prince has a specific constitutional role.

Neither the Danish or Norwegian constitutions currently specify the title of the oldest child of the monarch or the heir to the throne. (To be clear, I am not disputing that it is the tradition to limit Crown Prince to the male heir apparent.)

 

[Muhler]

The Law of Succession §6 of 2009: Upon the death of the monarch (or abdication), the throne passes to oldest child of the monarch.

The Constitution of 1953 §7,8 & 9 specifically mention the Successor. (Which is also means Crown Prince, Heir or Hereditary Prince. Just as King also means Queen Regnant, Regent or Rigsforstander.)

The Constitution of 1953 §7,8 & 9 specifically mention the Successor. (Which is also means Crown Prince, Heir or Hereditary Prince. Just as King also means Queen Regnant, Regent or Rigsforstander.)

Correct. The Constitution uses the term "tronfølger" (heir to the throne), rather than "Kronprins". (And I realize that it is the tradition for a "tronfølger" who is the King's eldest son to be known as Crown Prince, whereas the title Crown Princess was traditionally carried by the wife of the Crown Prince or, when he was unmarried, the eldest daughter of the King if unmarried.)

 

[Tatiana Maria]

My understanding is that the term "Crown Prince" in Scandinavia applies to the heir apparent to the throne whereas "Hereditary Prince" in Knud's case was a title that applied to a male heir presumptive.

After consulting the former wording of the Constitution, it seems that under the old laws in Norway, the term Crown Prince only applied to the heir apparent if he was the son of the King.

What I don't understand is why Prince Knud was only called Tronfølger and not Arveprins as expected between 1947 and 1953. Does that say something about King Frederik IX? For example, that from the start he didn't want his brother to succeed and pushed for changes in the Act of Succession?

Second question: now that equal primogeniture is in place, do you think a future female heir apparent will be called Kronprinsesse like in Sweden, rather than simply Tronfølger as Princess Margrethe was as heir presumptive?

As I said, there were other heirs presumptive who did not receive the Arveprins title. (In fact, only two of them did.) Most recently, Prince Christian Frederik did not receive it between 1808 and 1839, and I don't think Prince Christian received it during the several months that he was heir presumptive in 1863.

And again, if he was showing favoritism towards his own family, then it is odd that he also discontinued the tradition of calling the unmarried eldest daughter of the King the Crown Princess when that title was not held by a wife of the Crown Prince.

Perhaps Christian (1863) was seen as a special case because he was not a King's brother or close relative to the previous monarch. Weren't Frederik, half-brother of Christian VII, and Ferdinand, brother of Christian VIII, called Arveprins ?

Tronfølger, Arveprins and Kronprins is the same thing constitutionally speaking. So it's not a question of being "only" Tronfølger or Arveprins.

After 1953 Prince Knud got the title official Arveprins, pretty much as a compensation, but also because there was a chance the throne would revert to his family, even to him personally.

Your second question is interesting. For a thousand years the Crown Princess has always been the princess who is married to the Crown Prince. So it might be confusing, in the same way as it was seen as confusing to give PH the title of king. (There are also loads of references in the legislation to king, rather than monarch, in the legislation, so that could be even more confusing.)
Yet it works fine in Sweden, where Victoria is always referred to and addressed Kronprinssessan.

 

[Tatiana Maria]

Yes, they were, but they were the special cases.

Between Frederik III's introduction of a formal law of succession in 1665 and the second modification of the law of succession in 1953, there were eight heirs presumptive who were not the eldest son of the King.

1. Georg (1670-1671) - brother of the King
2. Carl (1699) - brother of the King
3. Louise (1747-1749) - sister of the King
4. Frederik (1766-1768) - half-brother of the King
5. Christian Frederik (1808-1839) - first cousin of the King
6. Frederik Ferdinand (1848-1863) - uncle of the King
7. Christian (1863) - first cousin of the King by marriage
8. Knud (1947-1953) - brother of the King

Only Frederik (1766-1768) and Ferdinand (1848-1863) received the title of Arveprins when first in line to the throne. Knud received it in 1953 in compensation for losing his position as heir presumptive.

 

[Tatiana Maria]

Your second question is interesting. For a thousand years the Crown Princess has always been the princess who is married to the Crown Prince.

Not always. As explained above, in the 17th and 18th centuries, the Crown Princess was at times the unmarried princess who was the eldest daughter of the King.

I am not sure when the Danish title of Crown Prince was created. But it is unlikely to be as ancient as a thousand years, since Denmark was not officially declared a hereditary monarchy until 1660.

Changing countries, wasn't the title of Princess of Asturias also held by the eldest living daugther of the monarch and had no brother, or who was the eldest sister of a childless king?

I believe that, as early as the 15th or 16th centuries, two daughters of Isabella the Catholic (Isabella and later Joanna) held the title of Princess of Asturias, although I think it was not automatic (proclamation by the Cortes was necessary, at least for Joanna ?).

More recently, in the 19th century, Maria de las Mercedes, daughter of Alfonso XII, was also Princess of Asturias. I am not sure if Queen Isabella II was ever formally Princess of Asturias, but she became queen at age 3, so maybe there wasn't enough time to formalize it?


EDIT: The constitution of 1978 and the Royal Decree 1368/1987 have now made the title automatic from the moment a person becomes the heir, either apparent or only presumptive.
