Answer:
Julius Caesar, the Roman dictator, was assassinated by a group of senators on the Ides of March (15 March) of 44 BC during a meeting of the Senate at the Theatre of Pompey in Rome. The senators stabbed Caesar 23 times. The senators claimed to be acting over fears that Caesar's unprecedented concentration of power during his dictatorship was undermining the Roman Republic, and presented the deed as an act of tyrannicide. At least 60 senators were party to the conspiracy, led by Marcus Junius Brutus, Gaius Cassius Longinus and Decimus Junius Brutus. Despite the death of Caesar, the conspirators were unable to restore the institutions of the Republic. The ramifications of the assassination led to the Liberators' civil war and ultimately to the Principate period of the Roman Empire.
Explanation:
The setting in this poem includes both time and place. The author first gives us a sense of both mood and time with the first line:
"Once upon a midnight dreary,"
We as readers are then told that the author/narrator is in his study, as evidence is given of the books, the bust of Pallas, and the other ecoutrements that lend themselves to studious labors. We are certain that this is, at the very least, a room, as Poe refers to his "chamber door" multiple times throughout the poem. In closing, we can conclude that this poem is set in the 1800s, on a dark and stormy night, in the author's place of academic study and leisure.
