St. Michael's Cathedral in Gyulafehérvár, in accordance with Unitarian rite. John Sigismund had made his last testament and will in the presence of Chancellor Mihály Csáky and Treasurer Gáspár Bekes during his earlier illness in the summer of 1567. Despite his recovery, he did not alter the text in the following years. He willed most of his wealth to his uncle, Sigismund August of Poland, and his three aunts, Sophia, Anna and Catherine. He bequeathed his library to the Protestant school of Gyulafehérvár. John Sigismund, who never married and left no heir, was the last member of the Zápolya family. In his will, he assured the Diet of its right to choose the new monarch. The representatives of the Three Nations elected the Roman Catholic Stephen Báthory, who adopted the title Voivode of Transylvania. Gáspár Bekes, supported by Maximilian II, contested the election, but Báthory emerged victorious in the resulting civil war and consolidated his rule.
