Alexandre Dumas' "The Count of Monte Cristo" is considered a classic for the same reason many other books are considered classics: it has stood the test of time. Completed in 1844, the novel has been in continuous print ever since, and has been adapted for film nine times, most recently in 2002. In addition, a new nonfiction book about the real-life model for "The Count of Monte Cristo" by Tom Reiss, "Black Count," tells the story of Alexandre Dumas' father, the son of a slave who rose up the ranks of the French Army to the rank of general.
"The Count of Monte Cristo" is a well-told story of betrayal and vengeance, with a little romance, themes that tend to be popular with the reading public. It is still read widely in schools, and continues to be popular.
