After the death of Elizabeth, who was willing to make peace with Wladyslaw, Jiskra remained on the hereditary king's side and made a pact with the occupied cities to secure Ladislaus' rule. In order to make peace Jiskra was invited by Wladyslaw to the Diet of April 1444 along with other supporters of Ladislaus. At the diet he defended Ladislaus' cause with such vehemency, that his violent behavior almost caused his death. Wladyslaw gallantly saved his life when he helped escape the disguised Jiskra to Győr, from where he went to Vienna to the court of Frederick III, Holy Roman Emperor, to visit Ladislaus.
