Throughout the twentieth century, The Adventures of Huckleberry Finn has become famous not only as one of Twain's greatest achievements, but also as a highly controversial piece of literature. In certain Southern states, the novel was banned due to its extensive criticism of the hypocrisy of slavery. Others have argued that the novel is racist due to the many appearances of the word "nigger." Unfortunately, the connotations of this word tend to override the novel's deeper antislavery themes, and prevent readers from understanding Twain's true perspective. In Twain's time, this word was used often and did not carry as powerful a racist connotation as it does currently. Therefore, in using the word, Twain was simply projecting a realistic portrayal of Southern society. Undoubtedly, The Adventures of Huckleberry Finn is highly significant due to its deep exploration of issues surrounding racism and morality, and continues to provide controversy and debate to this day, evidencing the continued relevance of these concepts.
