Afterward, he enlisted in the U. S. Army and rose to the rank of sergeant major. He was expelled from West Point after a year, loosing his hopes of becoming a career officer. Poe started publishing his poetry and stories in the early 1830s and pursued a career in journalism to ensure some sort of financial security. In 1843, he published several works, including The Tell-Tale Heart and The Gold Bug which won a $100 prize in a contest sponsored by the Philadelphia Dollar Newspaper. The story made Poe famous with the fiction reading public. His poem 'The Raven' which appeared in the New York Evening Mirror in January 1845, was a critical and commercial success. Along with 'To Helen' and 'Annabel Lee', 'The Raven' is considered one of Poe's finest poems. The Fall of the House of Usher and The Murders in the Rue Morgue are arguably two of his best short stories. But both Poe and his wile Virginia's poor health kept the pair in financial and emotional distress. Poe died in 1849. When did Poe start publishing his poetry and stories and pursue a career in journalism?
A.
In the early 1810s.
B.
In the early 1820s.
C.
In the early 1830s.
