In the Vasas and Jagiellos conference in Turku on 12 December, I will talk, among other things, about Princess Anna of Sweden (1568-1625), the Lutheran sister of the Catholic king Sigismund Vasa. Recently, I published a short biography and a translation of her letter. It is included in this collection edited by Kirsi I. Stjerna. #Vasa #Jagiello #Reformation #Princesses #WomenReformers #History
