Droit du seigneur
In Mozart's "The Marriage of Figaro", which premiered in 1786 with a libretto by Lorenzo Da Ponte, the comic plot revolves around the successful efforts of the young bride and groom, Figaro and Susanna, to block the efforts of the unfaithful Count Almaviva to seduce Susanna. To achieve his aim, the frustrated Count threatens to reinstitute "droit du seigneur". It was based on a play by Pierre Beaumarchais.
Maria Theresa of Austria (1767–1827)
The premiere could not be arranged in time, however, so the opera "The Marriage of Figaro" was substituted on the express orders of Maria Theresa's uncle, Holy Roman Emperor Joseph II. The choice of "The Marriage of Figaro" was considered improper for a new bride by many observers, and the couple left the opera theater early without seeing the entire work performed. Mozart complained bitterly of the intrigues surrounding this incident in a letter to his friend Gottfried von Jacquin that was written in stages between 15 October and 25 October 1787. She was also present in Prague in September 1791 for the premiere of Mozart's opera "La clemenza di Tito", which was written as part of the celebrations there in honor of the coronation of her father as King of Bohemia.
