I've asked in one or two threads about the Vasas (both in Poland and in Sweden) and the continuation of their lines somehow, but with the latest reply to the Earlier Jagiellonika Weddings thread, I was wondering what might have happened if Wladyslaw IV or Jan II Kazimierz's daughter had survived.
I can't seem to find out what caused the death of Jan II's daughter - Maria Anna Tereza - but I seem to recall that Wladyslaw IV's - Maria Anna Isabella - died of epileptic seizures.
What would have happened if one of those girls had survived her father? Would she have been elected "king" at the death of her father or half-uncle. After all Poland had had two female kings before - Hedwig of Hungary, Grand Duchess of Lithuania and Anna Jagiellonika, Princess of Transylvania. And if the girl is elected and still underage, who might the regent be? The Interrex? Her stepmother, Maria Ludwika? A Regency Council?
