Stephen Báthory
Sigismund was the son of Christopher Báthory and his second wife, Elisabeth Bocskai. He was born in Várad (now Oradea in Romania) in 1573, according to the Transylvanian historian, István Szamosközy. At the time of Sigismund's birth, his uncle, Stephen Báthory, was the voivode of Transylvania. After being elected King of Poland in late 1575, Stephen Báthory adopted the title of Prince of Transylvania and made Sigismund's father voivode. Stephen Báthory set up a separate chancellery in Kraków to supervise the administration of the principality.
