The Three Musketeers is a historical adventure novel written by French author Alexandre Dumas, first published in serial form in 1844. Set between 1625 and 1628, it recounts the adventures of a young man named d'Artagnan after he leaves home to travel to Paris, hoping to join the Musketeers of the Guard. Although d'Artagnan is not able to join this elite corps immediately, he befriends three of the most formidable musketeers of the age β Athos, Porthos, and Aramis β and becomes embroiled in affairs of state and court.
The novel is celebrated for its swashbuckling action, memorable characters, and intricate plotting involving political intrigue, romance, and betrayal. It explores themes of honor, friendship, and loyalty, famously encapsulated in the musketeers' motto: "All for one, and one for all." The story draws loosely on historical figures and events, including Cardinal Richelieu, King Louis XIII, Queen Anne, and the Duke of Buckingham.
One of the most widely read French novels, The Three Musketeers has been adapted countless times across virtually every medium, including film, television, stage, and comics. Its enduring popularity has made d'Artagnan and the three musketeers archetypal figures in popular culture, and the novel remains a cornerstone of classic adventure literature.
