Oktoberfest

In the era of National Socialism, Oktoberfest was used as part of Nazi propaganda.

An excerpt from the article 20 facts about Oktoberfest
The Jews were forbidden to work during the organization of the festival. On the 125th anniversary of the holiday, a great Nazi-led jubilee parade was organized in 1935, and when Hitler annexed Austria in 1938, the Oktoberfest was renamed the "Great German Folk Festival". In the post-war period, only the "fall festival" took place, and the first post-war Oktoberfest was held in September 1949.
