Bayreuth those institutions was never reversed. Being a stronghold of right-wing parties since the 1920s, Bayreuth became a center of Nazi ideology. In 1933, it was made capital of the Nazi Gau of Bavarian Ostmark ("Bayerische Ostmark", in 1943 "Gau Bayreuth"). Nazi leaders often visited the Wagner festival and tried to turn Bayreuth into a Nazi model town. It was one of several places in which town planning was administered directly from Berlin, due to Hitler's special interest in the town and in the festival. Hitler loved the music of Richard Wagner, and he became a close friend of Winifred Wagner
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".
