With the birth of Queen Victoria's baby girl, there is one more female heir to the throne.So, if we put the current reigning royal houses, the female primogeniture generally wins.Here I mean the future royals (as the equal law hasn't been adopted many years ago).But I wish to clarify some questions.
So, I believe all non-European reigning houses don't accept the female heirs. In this way, if I'm not mistaken , there are 10 European reigning monarchies, most of which have female heirs( and mainly equal primogeniture).
1.Britain ( we'll have to wait for the baby of Cambridges, but the equal law seems to be adopted);
2.Belgium ( female heir);
3.Denmark (male heir);
4.Holland (female heir);
5.Norway (female heir);
6.Sweden (female heir);
7.Spain ( I think Leonor will remain heir unless Letizia gives birth to a boy);
8.Monaco ( we'll have to wait);
9.Luxembourg ( we'll have to wait);
10.Liechtenstein ( here I have little knowledge).
In case of European houses I don't know the precise situation with Britain, Monaco and Lichtenstein. Has there been discussed or adopted the equal law?
