From 1640, he was Obersthofmeister (Lord Chamberlain) and teacher of Ferdinand IV, who was King of the Romans at the time.

[2] In 1653, Emperor Ferdinand III raised him to Imperial Prince and in 1654, in his capacity as King of Bohemia, enfeofed him with the Duchy of Münsterberg and the City of Frankenstein.

He was, however, suspected of having had secret talks with King Louis XIV of France, who was alleged to have promised him a post as Cardinal and was suddenly relieved of his duties on 10 December 1669 and banished from the court.

In 1673, he inherited the Lordships of Gottschee and Žužemberk from his elder brother Wolf Engelbrecht, Count of Auersperg.
