Anton Florian (born 1656, died 1721) had been prepared thoroughly for assuming political offices. Already in 1691 he was ambassador at the papal court in Rome. In 1695, he became Chief Intendant of the royal palace of the young Archduke Karl, being in charge of the latter's education.
During the Spanish War of Succession he went to Spain together with Karl, where he was chief intendant and prime minister of the archduke. When the latter became Emperor Karl VI, after the sudden death of his brother in 1711, Anton Florian returned to Vienna, too, where he was a central political figure as imperial chief intendant and chairman of the Secret Council until his death.
