He was sent to offer the Hungarian crown to the archduke Ferdinand, and on his Coronation (Nov. 3rd, 1527) was made commandant of Buda. On the capture of Buda by Suleiman the Magnificent, Nádasdy went over to John Zapolya. In 1530 he successfully defended Buda against the imperialists. In 1533 his jealousy of the dominant influence of Ludovic Gritti caused him to desert John for Ferdinand, to whom he afterwards remained faithful. ”
