The Danish Sisters

Queen Anne Marie does outrank her older sister in Denmark. Unless, ofcourse Benedicte is Guardian of the Realm, ie. Acting Monarch.
Anne Marie did get her father's approval for her marriage, but the loss of succession rights was thought to be automatic. Had she not married at the age of 18, she would have become member of the Council of State at the age of 21 and been able to act as Guardian of the Realm and fulfil the duties of a heiress.
The fact that King Frederik approved the marriage of Margrethe to Henrik had nothing to do with the fact that he was a count, but that he was a prospective husband to a daughter who even her self doubted she would ever meet someone to marry.
Noone knows why King Frederik did not approve his nephew's marriages. Perhaps they married Danes? Or because he wanted to limit the number of Princes? There were no laws or regulations, the decision was his alone.
I checked the background for Prince Henriks countly title and google translated from Wikipedia (See the explanation elsewhere):
In 1655 Prince Henrik's 5 x great grandfather Jean Laborde was granted a noble patent by the French king Louis 14. In the ancien régime ie. before 1792, all noble titles were feudal, ie bound to a land area. As Laborde's property was not in France but in Béarn, a fully independent state in the French Empire, it meant that Louis XV's nobility was not French, but belonged to Béarn and thus had to be approved by Béarn's government in Navarre. This was rejected twice, in 1703 and 1707, which effectively made the nobility and the family thus neither noble in France nor Béarn. Béarn very staunchly defended its independence, so it is obvious to assume that the refusals had nothing to do with Laborde, but have been a political opposition to getting the French-minded nobility in the back door.
Princess Irene and her fiance Carlos Hugo of Bourbon-Parma did not want her to loose her succession rights. It took several cabinet members, her parents and sisters to make the couple understand that the number 2 in line of succession could not retain that position when she married a Carlist pretender to the Spanish throne. At the same time Irene's conversion to Catholicism had come out just shortly before and that had angered parts of the Protestant community for whom the House of Orange represents the fight of the protestant Dutch against the Catholic Spanish king.
Had Carlos Hugo's father not taken on the Carlist role and had he been the heir to the titular Duke of Parma and Piacenza the marriage might have received consent and Irene and her family would have played the role taken up by her younger sister Margriet.
The one advantage that would have had in my view is that the ridiculous title of count(ess) of Orange-Nassau van Amsberg would not have been used for Beatrix' dynastic grandchildren.
Prince Claus was never a count. He was simply a Von Amsberg untitled lower German nobility. When he married the position was translated to the Dutch nobility and he became a jonkheer van Amsberg. The title of count or countess was invented for his grandchildren by his two younger sons. A bad idea when it came to Friso's descendant as they were not dynastic so keeping the name of Orange-Nassau for a non-dynastic line could cause trouble. It also does not work for Constantijn's line either. They are the grandchildren of a sovereign from a dynastic match but not even HH prince(ss) of Orange-Nassau as in the previous generation.
In Denmark, Margreth married a mere Count, the next sister Benedikte, a Prince and the youngest, Ann-Marie, a King !
I've learned that the late Prince Hendrik was not even bon to real nobility. Rather, he was a member of the faux nobility: the comital title was created for the Monzapat family. Evidently his father-in-law, King Frederik IX of Denmark, was unaware of the situation and thought that his future son-in-law was a genuine nobleman. It had to be a sore point later on for his nephews, whose marriages to commoners were unapproved, since *Count Henri* was actually technically one himself.
Did Ann-Marie outrank her sister Benedikte in Denmark ?
I don't believe so, anymore than Benedikte outranked HER older sister simply for being married to a prince whose house is listed in the second section of the ALMANACH DE GOTHA. Like I said, in reigning houses, rank depends on genealogical seniority -- as long as the marriages are all dynastically approved.
Interestingly enough, the problem with Anne-Marie's marriage was not the *equality* of her husband's birth (duh), as it was the fact that he was the heir-apparent to a foreign reigning house. The Danish constitution forbids the sovereign to be the king or queen of another country. So she forfeited her place in the line of succession to the throne of Denmark, on the occasion: as with the Dutch princesses (who, according to the constitution of the Netherlands, were not allowed to renounce their succession rights, but could nevertheless forfeit them by marrying without the consent of Parliament), I'm assuming that she didn't even seek her father's consent.
Speaking of the Dutch sisters: a similar situation could be observed of the daughter of the late Queen Juliana. The eldest, who succeeded her on the throne as Queen Beatrix, married only a minor German nobleman, Count Claus von Amsberg (born only a tad bit higher than Count Henri de Monzapat, who like I said was not really a member of the French nobility by birth; at least Claus was a genuine nobleman). By contrast, the second daughter married a royal prince of *equal* birth, who would eventually become head of the house of Bourbon-Parma. Of course, the two younger daughters (unlike Princess Anne-Marie of Denmark) married untitled commoners ...
So Princess Irene was the only daughter of her parents to make a royal marriage. Because she married without the consent of the Dutch parliament, the union is non-dynastic. By contrast, her sister Margriet retained her succession rights by seeking and receiving consent for her marriage. Her situation might be comparable to that of Princess Benedikte, who received consent for her marriage and has a place in the royal life of Denmark (although her children forfeited their places in the Danish succession by failing to reside in the country).
However, in international social circles, I believe Anne-Marie outranks Benedikte; and it's conceivable that Irene outranks her younger sisters.
