Prior to Harry Potter, fantasy literature (e.g. Lord of the Ring) and games (e.g. Dungeons and Dragons) were  banned from many schools, with conservative groups claiming they spread belief in the occult. Harry Potter was initially banned in many schools with conservative parent groups claiming it promoted witchcraft! However Harry Potter's popularity forced school boards to address the fantasy genre. There were many debates and even some lawsuits, but ultimately Harry Potter took down conservative censorship in schools and libraries.
