A short story is a work of fiction that is usually written in prose, often in narrative format. A short story usually deals with a few characters and often concentrates on the creation of the mood rather than the plot.

The short story format tends to be more pointed than longer works of fiction, such as novellas (in the 20th and 21st century sense) and novels. Short story definitions based on length differ somewhat, even among professional writers, in part because of the fragmentation of the medium into genres. Since the short story format includes a wide range of genres and styles, the actual length is determined by the individual author's preference (or the story's actual needs in terms of creative trajectory or story arc) and the submission guidelines relevant to the story's actual market. Guidelines vary greatly among publishers.

Many short story writers define their work through a combination of creative, personal expression, and artistic integrity. They attempt to resist categorization by genre as well as definition by numbers, finding such approaches limiting and counter-intuitive to artistic form and reasoning. As a result, definitions of the short story based on length splinter even more when the writing process is taken into consideration.

Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), better known by his pen name Mark Twain, was an American author and humorist. He is most noted for his novels, The Adventures of Tom Sawyer (1876), and its sequel, Adventures of Huckleberry Finn (1885), the latter often called "the Great American Novel."

Twain grew up in Hannibal, Missouri, which would later provide the setting for Huckleberry Finn and Tom Sawyer. He apprenticed with a printer. He also worked as a typesetter and contributed articles to his older brother Orion's newspaper. After toiling as a printer in various cities, he became a master riverboat pilot on the Mississippi River, before heading west to join Orion. He was a failure at gold mining, so he next turned to journalism. While a reporter, he wrote a humorous story, "The Celebrated Jumping Frog of Calaveras County", which became very popular and brought nationwide attention. His travelogues were also well-received. Twain had found his calling.

He achieved great success as a writer and public speaker. His wit and satire earned praise from critics and peers, and he was a friend to presidents, artists, industrialists, and European royalty.

Ernesto "Che" Guevara (Spanish pronunciation: [ˈtʃe ɣeˈβaɾa]; June 14, 1928 – October 9, 1967), commonly known as el Che or simply Che, was an Argentine Marxist revolutionary, physician, author, intellectual, guerrilla leader, diplomat, and military theorist. A major figure of the Cuban Revolution, his stylized visage has become a ubiquitous countercultural symbol of rebellion and global insignia within popular culture.

As a young medical student, Guevara traveled throughout Latin America and was radically transformed by the endemic poverty and alienation he witnessed. His experiences and observations during these trips led him to conclude that the region's ingrained economic inequalities were an intrinsic result of capitalism, monopolism, neocolonialism, and imperialism, with the only remedy being world revolution. This belief prompted his involvement in Guatemala's social reforms under President Jacobo Arbenz, whose eventual CIA-assisted overthrow solidified Guevara's political ideology. Later, while living in Mexico City, he met Raúl and Fidel Castro, joined their 26th of July Movement, and sailed to Cuba aboard the yacht, Granma, with the intention of overthrowing U.S.-backed Cuban dictator Fulgencio Batista. Guevara soon rose to prominence among the insurgents, was promoted to second-in-command, and played a pivotal role in the victorious two-year guerrilla campaign that deposed the Batista regime.
