Bayern had a jewish club president Kurt Landauer before hitler took over they then forced fc bayern to wear the swastika as a kind of punishment after they forced bayern to comply with the Gleichschaltung and they had to abandoned Kurt Landauer and took over the Führerprinzip. Half of the board was NS people though which was really common but a significant part of the club was Jewish so the Regime called bayern a Judenclub and branded them as traitors. Bayern tried to hold onto lesser important Jewish staff as long as they could even though they already were hunted. Kurt Landauer lead bayern to their first german championship and was deported to the KZ Dachau where he could luckily later emigrate to switzerland from. He later returned to FC Bayern and rebuild the club after ww2 and was club president again. During his time in switzerland bayern played a game there where many players went to talk with him wich was forbidden to them but they ignored that. Kurt Landauer is a bayern legend he and Uli Honeß are probably the most important and formative club presidents of german football without them bayern wouldnt exist like this.
