It is the matriarchy of European royalty: three sisters whose birth forced to suppress the sallic law in their country, Denmark, so that the greatest could reign.King Federico IX of Denmark had waited, along with his wife, Queen Ingrid, until the last moment a child was born, but instead had three daughters: Margarita, the heiress, Benedicta and Ana María.They have an excellent relationship, full of complicity.They rely on family celebrations, spend vacations together and even Christmas.
