(b Wiener Neustadt, 22 March 1459; reg 1493–1519; d Wels, 12 Jan 1519).
Son of Frederick III. Through his marriage and those of his children and grandchildren, he contributed substantially to the territorial aggrandisement of the Habsburgs in the Netherlands, Spain and eastern Europe. His patronage tended largely to the glorification of the dynasty, notably in portraiture and in the large statues of his family and ancestors he commissioned for his tomb in Innsbruck. His autobiographical literary works reflect his medieval courtly ideals and were illustrated by major contemporary artists. He was also probably the greatest patron of armourers in the late 15th century.
