With few chances to take part in the politics of the Electorate of Saxony or receive any land from his older brother Frederick Augustus III, Anton lived under the shadows.

Mozart's opera Don Giovanni was originally intended to be performed in honor of his bride for a visit to Prague on 14 October 1787, as she traveled between Vienna and Dresden for the in-person ceremony, and librettos were printed with mention of the names of both Anton and the archduchess.

The choice of The Marriage of Figaro was considered improper for a new bride by many observers, and the archduchess left the opera theater early without seeing the entire work performed.

Anthony was present in Prague in September 1791 for the first performance of Mozart's opera La clemenza di Tito, which was written as part of the coronation ceremonies of his father-in-law, the Emperor Leopold II, as King of Bohemia.

Because the people wished to have a younger regent, Anthony agreed to appoint his nephew Frederick Augustus Prince Co-Regent (de: Prinz-Mitregenten).

[6] The king kept his exclusive sovereignty but was bound by the Government Business to cooperate with the Ministers and the decisions of both Chambers of the Estates (de: Kammern der Ständeversammlung) meeting.
