A big thing that this book said on society was that it went against slavery which was very controversial at the time.
The book was banned from many school because it used the n word. Others see Adventures of Huckleberry Finn not as an attack on racism, but as inherently racist itself. African Americans and others, led by the NAACP, begin to challenge the book in the 1950s, appalled by the novel's portrayal of the slave Jim and its repeated use of the n word.
The book is removed from some schools in the New York City school system, and its place on required reading lists is threatened in other cities.
