Edgar Poe was born in Boston, Massachusetts, on January 19, 1809, the second child of American actor David Poe Jr. and English-born actress Elizabeth Arnold Hopkins Poe. He had an elder brother, Henry, and a younger sister, Rosalie. Their grandfather, David Poe, had emigrated from County Cavan, Ireland, around 1750.

His father abandoned the family in 1810, and his mother died a year later from pulmonary tuberculosis. Poe was then taken into the home of John Allan, a successful merchant in Richmond, Virginia, who dealt in a variety of goods, including cloth, wheat, tombstones, tobacco, and slaves. The Allans served as a foster family and gave him the name "Edgar Allan Poe", although they never formally adopted him.

The Allan family had Poe baptized into the Episcopal Church in 1812. John Allan alternately spoiled and aggressively disciplined his foster son. The family sailed to the United Kingdom in 1815, and Poe attended a grammar school for a short period in Irvine, Ayrshire, Scotland, where Allan was born, before rejoining the family in London in 1816. There he studied at a boarding school in Chelsea until summer 1817. He was subsequently entered at the Reverend John Bransby's Manor House School in Stoke Newington, then a suburb 4 miles (6 km) north of London.

Poe moved to Richmond with the Allans in 1820. In 1824, he served as the lieutenant of the Richmond youth honor guard as the city celebrated the visit of the Marquis de Lafayette. In March 1825, Allan's uncle and business benefactor William Galt died, who was said to be one of the wealthiest men in Richmond, leaving Allan several acres of real estate. The inheritance was estimated at $750,000 (equivalent to $20,000,000 in 2023). By summer 1825, Allan celebrated his expansive wealth by purchasing a two-story brick house called Moldavia.

Poe may have become engaged to Sarah Elmira Royster before he registered at the University of Virginia in February 1826 to study ancient and modern languages. The university was in its infancy, established on the ideals of its founder, Thomas Jefferson. It had strict rules against gambling, horses, guns, tobacco, and alcohol, but these rules were mostly ignored. Jefferson enacted a system of student self-government, allowing students to choose their own studies, make their own arrangements for boarding, and report all wrongdoing to the faculty.

The unique system was rather chaotic, and there was a high dropout rate. During his time there, Poe lost touch with Royst…

As Poe was unable to support himself, he decided to enlist in the United States Army as a private on May 27, 1827, using the name "Edgar A. Perry". Although he claimed that he was 22 years old, he was actually 18. He first served at Fort Independence in Boston Harbor for five dollars a month. That same year, his first book was published, a 40-page collection of poetry titled Tamerlane and Other Poems, attributed only to "A Bostonian". 50 copies were printed, and the book received virtually no attention. Poe's 1st Regiment of Artillery was posted to Fort Moultrie in Charleston, South Carolina, before embarking on the brig Waltham on November 8, 1827. Poe was promoted to "artificer", an enlisted tradesman tasked with preparing shells for artillery. His monthly pay doubled. Poe served for two years, attaining the rank of sergeant major for artillery, the highest rank that a non-commissioned officer could achieve. He then sought to end his five-year enlistment early.

Poe revealed his real name and his actual circumstances to his commanding officer, Lieutenant Howard, who promised to allow Poe to be honorably discharged if he reconciled with Allan. Poe then wrote a letter to Allan, who was unsympathetic and spent several months ignoring Poe's pleas. Allan may not have written to Poe to inform him of his foster mother's illness. Frances Allan died on February 28, 1829. Poe visited the day after her burial. Perhaps softened by his wife's death, Allan agreed to support Poe's desire to receive an appointment to the United States Military Academy at West Point, New York.

Poe was finally discharged on April 15, 1829, after securing a replacement to finish his enlistment. Before entering West Point, he moved to Baltimore, where he stayed with his widowed aunt, Maria Clemm, her daughter Virginia Eliza Clemm (Poe's first cousin), his brother Henry, and his invalid grandmother Elizabeth Cairnes Poe. That September, Poe received "the very first words of encouragement I ever remember to have heard" in a review of his poetry by influential critic John Neal, which prompted Poe to dedicate one of the poems to Neal in his second book, Al Aaraaf, Tamerlane and Minor Poems, published in Baltimore in 1829.

Poe traveled to West Point and matriculated as a cadet on July 1, 1830. In October 1830, Allan married his second wife Louisa Patterson. This marriage and the bitter quarrels with Poe over children born to Allan out of extramarital affairs led to the foster father finally disowning Poe. Poe then decided to leave West Point by intentionally getting court-martialed. On February 8, 1831, he was tried for gross neglect of duty and disobedience of orders for refusing to attend formations, classes, and church. Knowing he would be found guilty, Poe pleaded not guilty to the charges in order to induce dismissal.

After his brother's death, Poe's earnest attempts to make a living as a writer were mostly unsuccessful. However, he eventually managed to earn a living by his pen alone, becoming one of the first American authors to do so. His efforts were initially hampered by the lack of an international copyright law. American publishers often chose to sell unauthorized copies of works by British authors rather than pay for new work written by Americans, regardless of merit. The initially anemic reception of Edgar Allan Poe's work may also have been influenced by the Panic of 1837.

There was a booming growth in American periodicals around this time, fueled in part by new technology, but many did not last beyond a few issues. Publishers often refused to pay their writers or paid them much later than they promised, and Poe repeatedly resorted to humiliating pleas for money and other assistance. After his early attempts at poetry, Poe turned his attention to prose, perhaps based on John Neal's critiques in The Yankee magazine. He placed a few stories with a Philadelphia publication and began work on his only drama, Politian. The Baltimore Saturday Visiter awarded him a prize in October 1833 for his often overlooked short story "MS. Found in a Bottle". The tale brought him to the attention of John P. Kennedy, a Baltimorean of considerable means who helped Poe place some of his other stories and introduced him to Thomas W. White, editor of the Southern Literary Messenger in Richmond.

In 1835, Poe became assistant editor of the Southern Literary Messenger, but White discharged him within a few weeks, allegedly for being drunk on the job. Poe then returned to Baltimore, where he obtained a license to marry his cousin Virginia on September 22, 1835, though it is unknown if they were actually married at that time. He was 26 and she was 13.

Poe was reinstated by White after promising to improve his behavior, and he returned to Richmond with Virginia and her mother. He remained at the Messenger until January 1837. During this period, Poe claimed that its circulation increased from 700 to 3,500. He published several poems, and many book reviews, critiques, essays, and articles, as well as a few stories in the paper. On May 16, 1836, he and Virginia were officially married at a Presbyterian wedding ceremony performed by Amasa Converse at their Richmond boarding house, with a witness falsely attesting Clemm's age as 21.
In 1838, Poe relocated to Philadelphia, where he lived at four different residences between 1838 and 1844, one of which at 532 N. 7th Street has been preserved as a National Historic Landmark.

That same year, Poe's only novel,
