Which French Romantic writer authored 'The Three Musketeers'?

Alexandre Dumas wrote the French Romantic adventure novel “The Three Musketeers.” It was published in 1844 and became the first novel in Dumas’s d’Artagnan Romances, followed by Twenty Years After and The Vicomte de Bragelonne.

The story is set between 1625 and 1628 and follows the young Gascon d’Artagnan as he travels to Paris hoping to join the Musketeers of the Guard. He becomes associated with Athos, Porthos, and Aramis, whose famous motto is “All for one, one for all.” The novel combines historical figures and political events with sword fights, intrigue, romance, and melodramatic adventure.

Dumas’s authorship is genuine, though he worked closely with Auguste Maquet, a collaborator who helped prepare plots and drafts for several novels. That collaboration does not make Balzac, Flaubert, or Victor Hugo alternative answers. The novel’s French title is Les Trois Mousquetaires, and its genre is often described as a historical novel or swashbuckler.
