Overview
Court Mistress or Chief Court Mistress is or was the title of the senior lady-in-waiting in the courts of Austria, Denmark, Norway, the Netherlands, Sweden, Imperial Russia, and the German princely and royal courts.
Austria
In 1619, a set organisation was finally established for the Austrian Imperial court which came to be the characteristic organisation of the Austrian-Habsburg court roughly kept from this point onward.
The first rank of the female courtiers was the Obersthofmeisterin, who was second in rank after the empress herself, and responsible for all the female courtiers. Whenever absent, she was replaced by the Fräuleinhofmeisterin, normally in charge of the unmarried female courtiers, their conduct and service.
