Bayreuth Festival banned her from administration of the Bayreuth Festival and its assets, which fell eventually to her two sons, Wolfgang and Wieland. During American occupation of the region after World War II, the theatre was used for army recreation and religious services for American soldiers. Only popular concerts and mixed entertainment were allowed: comedy, dancing, acrobatics, and then only "Die Fledermaus" was staged. When the Festival House was handed over to the city of Bayreuth in 1946, it was used for concerts of the Bayreuth Symphony Orchestra and the performances of such operas as "Fidelio", "Tiefland", "Madama Butterfly" and "La traviata".
