Answer:
The Inquisition is the historical context that frames Poe’s short story.
Step-by-step explanation:
The unnamed narrator has been sentenced to death and relates his violent experience, which despite being a fictional account of an unlikely event, it´s an accurate depiction of how violent the Inquisition was. In this sense, Inquisition is a great subject or setting for the genre of horror, given its explicitly violent events, which Poe enhances to conceive a suspenseful story, with only an implicit political agenda to condemn the Inquisition.
