偽ドミトリー1世
Ignatius was reported to be of Cretan descent. He came to Russia in 1595 as a member of an ecclesiastic mission, sent by the Patriarch of Constantinople. He took part in the coronation of Boris Godunov. In the early 17th century, Ignatius was appointed Archbishop of Ryazan. After the death of Godunov, he expressed support to False Dmitriy I and, even before the pretender reached Moscow, was swearing in his supporters in Tula. On 30 June 1605, Ignatius was elected patriarch by the council of bishops to replace Patriarch Job, who was sent into exile for refusing to acknowledge the pretender's rights for Russian throne. Ignatius performed the coronation of False Dmitriy I on 21 July 1605 and later also celebrated the coronation of his wife Marina Mnishek and their marriage. At that time, Ignatius was also an ardent opponent of the Unia.
