What organization did the woman, who Märta Ulfsdotter was the head lady in waiting of, found?
Margaret I of Denmark Margaret I (Danish: "Margrete Valdemarsdatter" , Norwegian: "Margrete Valdemarsdatter" , Swedish: "Margareta Valdemarsdotter" , Icelandic: "Margrét Valdimarsdóttir" ; 1353 – 28 October 1412), was queen consort of Norway 1363-1380 and Sweden 1363-1364, and later ruler in her own right of Denmark, Norway and Sweden, from which later period there are ambiguities regarding her specific titles. She was the founder of the Kalmar Union, which spanned Scandinavia for over a century. Margaret was known as a wise, energetic and capable leader, earning the nickname "Semiramis of the North", or "the Lady King". Though the latter was a derisive nickname invented by her rival Albert of Mecklenburg, it became widely used in recognition of her capabilities.
Ursulines The term Ursulines refers to a number of religious institutes of the Catholic Church. The best known group was founded in 1535 at Brescia, Italy, by St. Angela Merici (1474–1540), for the education of girls and the care of the sick and needy. Their patron saint is Saint Ursula. They are divided into two branches, one being the monastic Order of St. Ursula (post-nominals O.S.U.), among whom the largest group is the Ursulines of the Roman Union, described in this article. The other branch is the Company of St. Ursula, commonly called the "Angelines", who follow the original form of life established by their foundress.
