Final answer:
The Count of Morcerf in 'The Count of Monte Cristo' is testified against by Haydée and others who expose his past crimes, leading to his disgrace.
Step-by-step explanation:
The question 'Who testified against the Count of Morcerf?' refers to a character in Alexandre Dumas's novel 'The Count of Monte Cristo.' In the novel, the Count of Morcerf, originally named Fernand Mondego, is ultimately exposed and testified against by several characters, contributing to his downfall.
Notably, his crimes of treason and betrayal are revealed during a trial in the Chamber of Peers, where the witnesses include Haydée, the daughter of Ali Pasha (whom he betrayed), and others who unveil his past misdeeds. This public exposure and testimony lead to his disgrace and his unfavorable fate.
In the novel 'The Count of Monte Cristo' by Alexandre Dumas, multiple witnesses testify against the Count of Morcerf, also known as Fernand Mondego. One of the key witnesses is Édouard de Villefort, who reveals the true identity and past actions of the Count.
Another witness is Baron Franz d'Épinay, who testifies to the Count's involvement in the affairs of the Ali Pasha and his family. Additionally, Luigi Vampa, a bandit leader, testifies against the Count by providing information about his criminal activities.
