Three of his four sons succeeded him as king of Sweden; Erik XIV, Johan III and Karl IX. One son, Magnus, had an illness and died rather young. He had five daughters of which we don't know so much. Not surprisingly, considering that daughters in those days were much less important than sons. Their advantage was that they got a good marriage, mostly to improve the family and contacts with other European dynasties. This book is about his daughters.
Katarina married Edzard II of Ostfriesland, and was probably the most successful of the daughters. They had ten children. She was a stability for her other sisters and spent her life helping them in their marriages and fights for their own rights.
Sofia was married to Magnus II of Sachsen-Lauenburg and had a terrible marriage with an abusive husband. They got one surviving son and five that died in young age. Her brothers and sisters tried to keep him away from her, which seems to have been a good idea. It seems difficult to find anyone who liked him, even in his own family.
Anna married Georg Johan of Pfalz-Veldenz-Lützenstein and Elisabet, Kristoffer of Mecklenburg. Their daughter Margareta Elisabet married Johan Albrekt II of Mecklenburg. Vorpommern Mecklenburg were later, after the thirty year war, to be part of Sweden for a time.
One may think that women in those days did not have to much to say. However, it seems that Gustav Vasa, although a harsh and irrational person himself, managed to raise his family in rather a 'modern' way. They daughters were strong and fought for their marriages and families. Gustav Vasa, who at the time, was one of the richest monarchs of Europe, gave a sum of 100 000 daler as a dowry for each of his daughters. That in a time when 20 000 daler was a lot. The only problem was that it was mostly Katarina and her husband, who married while Gustav Vasa was still alive, that got the benefit of the dowry. Once Erik XIV became king, the fortune dwindled away at a high speed. The following brother kings had difficulties to keep up the promise given by their father. The dowries were paid in instalments, and part of them, not at all.
