Zbyněk Zajíc of Hazmburk
While he was initially a supporter of Czech religious reformer Jan Hus,[2] he later strongly opposed his views and reformatory effort.Originally Zbyněk respected well educated Jan Hus, tolerating and protecting him in his reforming endeavour despite the complaining clergy.While the king approved of the council and the newly elected Antipope Alexander V, Archbishop Zbyněk remained loyal to Pope Gregory XII.When Wenceslaus had refused to recognise any of the three existing popes (at the time) and wished to await the outcome of the council at Pisa, Zbyněk had put an interdict (Czech: klatba) on "all who obeyed the king", meaning Bohemia in general.In September 1409 he acknowledged antipope Alexander V and, with papal blessing, he ordered the heretical works burned,[3] and proclaimed an interdict against Hus.
