Wasa, Kristina
The Queen of Sweden from 1644 to 1654, during which time she acted in European politics and heavily patronised art, the philosophically minded Christina left her throne, not through death, but through conversion to Roman Catholicism, abdication and resettlement in Rome.
An excellent biography of Kristina Wasa by your Guide to Women's History.
Topped and tailed by a quotation and a bibliography, this descriptive timeline covers her life and rule.
Lavishly designed, this excellent site contains plenty of information about Christina of Sweden. Small discussions of her personal life, religion and impact on the world are accompanied by long timelines narrating her life, quotations and biographies of related individuals.
