In 1633, Ebba Leijonhufvud was appointed Mistress of the Robes to the underage monarch, queen Christina, with responsibility for the ladies-in-waiting of the queen. She kept this office for one year and was succeeded by
Elisabeth Gyllenstierna. After the death of the queen's foster mother and aunt
Catherine of Sweden, Countess Palatine of Kleeburg, the Royal Regency Council under
Axel Oxenstierna saw a need to appoint a new foster mother to the underage monarch (her mother being exiled), which resulted in a reorganization of the queen's household. In order to avoid the young queen from being dependent upon a single individual and favorite mother figure, the Royal Council decided to split the office of head lady-in-waiting (responsible for the queen's female courtiers) and the office royal governess (or foster mother) in four, with two women appointed to share each office. Accordingly, in 1639 Ebba Leijonhufvud and
Christina Natt och Dag was appointed to share the position of royal governess and foster mother with the title
Upptuktelse-Förestånderska ('Castigation Mistress'), while
Beata Oxenstierna and
Ebba Ryning was appointed to share the position of head lady-in-waiting, all four with the formal rank and title of
Hovmastarinna. This signified a permanent reorganization of the Swedish Royal Household: previously, there had been only one Mistress of the Robes with the title
Hovmästarinna ('Court Mistress'), but now, Beata Oxenstierna was additionally given the newly invented title of
Överhovmästarinna ('Chief Court Mistress'), and from the reign of Christina onward, there were to be one or two
Hovmästarinna and one
Överhovmästarinna at the Swedish Royal Court. The choice of Ebba Leijonhufvud and Christina Natt och Dag to the office of foster mother was officially motivated by their mutually reputed qualities of "honesty and virtue, seriousness and steadfastness", and in the case of Leijonhufvud in particular, her ideally educated daughter Anna Margareta was noted as an example of the great ability of her mother in raising a child. In 1639 she mentions her attitude toward her ladies in waiting in regard to Beata Oxenstierna and her daughter, maid of honor Märta Ulfsparre: "The Mistress of the Robes Lady Beata Oxenstierna and her daughter arrived just now. The more of them that comes here the worse it is" [...] "I despised everyone in my surroundings, particularly the women of my household, from whom I could not stand the smallest reproach." In 1642, her colleague, Christina Natt och Dag, died, and Christina was declared to be of legal maturity in 1644. Because her only child died childless before her, Ebba Leijonhufvud appointed her former son-in-law Johan Oxenstierna as her heir. ==References==
