After the 1876 festival, "Das Rheingold" was not seen again at Bayreuth for 20 years, until Cosima revived the "Ring" cycle for the 1896 festival. Meanwhile, opera houses across Europe sought to mount their own productions, the first to do so being the Vienna State Opera, which staged "Das Rheingold" on 24 January 1878. In April 1878 "Das Rheingold" was produced in Leipzig, as part of the first full "Ring" cycle to be staged outside Bayreuth. London followed suit in May 1882, when "Rheingold" began a cycle at Her Majesty's Theatre, Haymarket, under the baton of Anton Seidl. In the years following the London premiere, "Ring" cycles were staged in many European capitals. In Budapest on 26 January 1889, the first Hungarian performance of "Das Rheingold", conducted by the young Gustav Mahler, was briefly interrupted when the prompt-box caught fire and a number of patrons fled the theatre.
