France
France prosecuted authors for obscenity and blasphemy throughout the 19th century, with high-profile trials against Flaubert (Madame Bovary) and Baudelaire (Les Fleurs du Mal) among the most famous. The principle of liberté d'expression is deeply embedded in French law and culture, and outright book bans became increasingly rare through the 20th century. France today is generally considered to have strong literary freedom, though some works have been banned on grounds of defamation or incitement.
