The Vienna Opera Ball (German: Wiener Opernball) is an annual Austrian society event which takes place in the building of the Vienna State Opera in Vienna, Austria on the Thursday preceding Ash Wednesday (a religious holiday). Together with the New Year Concert, the ball is one of the highlights of the Viennese carnival season. History The tradition of the ball goes back to 1814 during the time when the crowned heads of Europe and the aristocracy searched for entertainment after the Napoleonic wars. The first ball in the opera house took place in 1877 as a soirée. The following balls were redoute, a French term for masquerade balls or costume parties, where the ladies wore their masks until midnight. From 1878 until 1899, such redoute balls took place around two to three times a year. The first redoute after World War I took place in 1921, with proceeds going to the pension fund of the two state theaters. These events were called also called Opernredoute. The first ball to be named "Opera Ball" was held in 1935 under the honorary patronage of the Federal Chancellor, but was suspended during World War II. It was revived after the war; it has been held annually ever since, with the exception of 1991, when it was cancelled due to the Persian Gulf War, and 2021 and 2022, both due to the COVID-19 pandemic. Since 2008, Desirée Treichl-Stürgkh has been the chairman (supervising organizer) of the Vienna Opera Ball. It is the highlight of the season, with the heads of state and government, the political and industrial elite, members of the high society, and their guests attending. The price for the entry tickets is the highest of all the Viennese balls. Starting in 1987, the Opernballdemo, a left-wing demonstration along the Ringstraße against the kind of capitalism represented by, as the protesters see it, many of the elite attending the ball, has regularly taken place on the same night. There have been occasional outbreaks of violence. This has almost disappeared since 2011, with protests focusing on the nationalist Akademikerball instead. In February 2020 the first same-sex couple were presented as debutante and escort at the ball. The two debutantes, Iris Klopfer and Sophie Grau, were from Germany. Klopfer wore the traditional white dress, long white gloves, and tiara typical for female debutantes while Grau, who is non-binary, wore the traditional black suit and tailcoats
