Legion of Decency- 1934

The birth of censorship, and do take the time to look at the list at the lower end of page you might be surprised at the Films listed

The National Legion of Decency was an organization dedicated to identifying and combating objectionable content, from the point of view of the Roman Catholic Church in the United States, in motion pictures. For the first quarter-century or so of its existence, the legion wielded great power in the American motion picture industry.
The Legion was founded in 1933 by Archbishop of Cincinnati John T. McNicholas as the Catholic Legion of Decency (CLOD) in response to an address given by apostolic delegate Archbishop Amleto Giovanni Cicognani at the Catholic Charities Convention in New York City. Cicognani warned against the "massacre of innocence of youth" and urged a campaign for "the purification of the cinema."
An important aspect of the studio system was the Production Code, which was implemented in 1934 in response to pressure from the Legion of Decency and public protest against the graphic violence and sexual suggestiveness of some sound films (the urban gangster films, for example, and the films of Mae West). The Legion had been established in 1933 by the American bishops of the Roman Catholic.
The Legion's ratings were applied to movies made in the United States (which were subject to the Production Code until 1967) as well as those imported from other countries. Beginning in 1968, the ratings were applied in addition to any rating assigned by the MPAA film rating system.
Legion-organized boycotts made a C rating harmful to a film's distribution and profitability. Accordingly, for the majority of years that the rating was applied, most condemned films were made outside of the United States, where their producers didn't have as much to fear from the condemnation. Of the 53 movies the Legion had placed on its condemned list by 1943, only Howard Hughes' The Outlaw came from a major US studio, and it had not been approved by the Production Code or distributed widely.1933
