what do you mean by "and they aren't."
Well, it is a very long story, in some of the previous 100 posts in this page it is all explained; btw, the Laws of House Savoy state that a member of the Family who marries without asking the permission of the Head of the Family automatically looses his rights to the Throne and all his titles, for himself and his descendants.
Please notice that, according to these rules, even a morganatic marriage needs the permission of the Head of the Family.
In the 1960s King Umberto in several letters, published in the website of Prince Amedeo of Savoy (
Real Casa di Savoia - Home) warned his son and at the time heir Vittorio Emanuele that He, the King, would not allow VE's marriage to a woman who was not of royal blood, since the Kings in House Savoy marry only Royal Princesses; in these letters, His Majesty warned VE also that if he would have married a commoner, the King would have informed the other Royal Families and the Italian people about VE violation of the Family Rules, and of his lost of the titles and rights.
In 1970 VE married Marina Ricolfi Doria in Las Vegas, and the following year in Teheran, without having asked the permission to his Father the King.
The logical consequence of the marriage is the lost of the rights and titles for him, and therefore for his future descendants; the other consequence is that the successor of King Umberto was the, at the time, second in the Line of Succession, Prince Amedeo.
Later, the King never recognised in any way the marriage of VE, nor as dinastyc nor as morganatic; moreover He also didn't tell anything against this marriage to the Italian people and the foreign Courts; finally, He gave his grandson Emanuele Filiberto the title of Prince of Venice.
These three facts has been read by VE as a dinastycal legitimation of his marriage, and therefore as a confirmation of his permanence in the Line of Succession and his titles; this reading is clearly against the Family Laws, that the Late King knew and always followed.
however i do amitt that the behaviour of the princes does not help a restoration of the monarchy in italy.
unfortunately that's true...and also seriously damage the image of the Royal Family.
