Gabriel von Salamanca
Gabriel von Salamanca (1489–1539) came from a merchant family of Burgos in Castile and was already a chancellor under Emperor Maximilian I by 1514.
When Archduke Ferdinand took over Austria in 1521, Salamanca became his general treasurer and archchancellor, opening the dynasty access to Fugger loans. He was enfeoffed with the County of Ortenburg in Carinthia in 1524. His measures and alleged self-serving conduct met fierce opposition from the nobility, and he was forced out in 1526.
He remained Ferdinand's adviser and retained his fiefs. In 1533 he began building a palace at Spittal an der Drau; he died at Ensisheim in 1539 before its completion.
