Gabriel von Salamanca-Ortenburg

Gabriel von Salamanca (1489 – 12 December 1539) was a Spanish nobleman who served as general treasurer and archchancellor of the Habsburg archduke (and future Emperor) Ferdinand I of Austria from 1521 to 1526.

Gabriel acted as Ferdinand's treasurer and archchancellor; he was vital in providing the Habsburg dynasty with access to loans by the Fugger family.

His economic measures, however, ultimately failed as his purported self-serving manners met with fierce opposition by the Austrian and Tyrolean aristocracy, who called him an "archarian Jew" and "stinking heretic".In 1523 he was elevated to the rank of an Imperial Freiherr (Baron) and Lord of Ehrenberg Castle in Tyrol as well as of Freyenstein and Karlsbach in Austria.

Salamanca nevertheless remained a close advisor of the archduke and was able to maintain his fiefs; he took his residence at Spittal an der Drau in Carinthia, where he had a luxuriant Renaissance palace built by Italian architects from 1533, today known as Schloss Porcia.

[8] His uncle Pedro de Salamanca (c. 1450–1529), was an ambassador of the Catholic Monarchs in London, and later prior of the Spanish Council or Nation in Bruges.
