After the 1896 revival, "Das Rheingold" was being performed regularly at the Bayreuth Festival, although not every year, within a variety of "Ring" productions. Until the Second World War, under the successive artistic control of Cosima (from 1896 to 1907), her son Siegfried (1908 to 1930) and Siegfried's widow Winifred (1931 to 1943), these productions did not deviate greatly from the stagings devised by Wagner for the 1876 premiere. With few exceptions, this generally conservative, even reverential approach – which extended to all Wagner's operas – tended to be mirrored in performances outside Bayreuth.
