Final answer:
Edmond Dantés is imprisoned for fourteen years in the Chateau d'If in 'The Count of Monte Cristo'.
Step-by-step explanation:
The character Edmond Dantès from the novel The Count of Monte Cristo by Alexandre Dumas is unjustly imprisoned in the Chateau d'If for fourteen years. This question does not relate to factual history but rather to the plot of a fictional piece of literature. Dantés is wrongfully accused of being a Bonapartist traitor, and without a proper trial, he is secretly incarcerated in the notorious prison fortress located off the coast of Marseille.
