First published in 1857, the book that collected these poems together, Les Fleurs du mal, was an instant sensation―earning Baudelaire plaudits and, simultaneously, disrepute. Only a year after Gustave Flaubert had endured his own public trial for published indecency (for Madame Bovary), a French court declared Les Fleurs du mal an offense against public morals and six poems within it were immediately suppressed (a ruling that would not be reversed until 1949, nearly a century after Baudelaire’s untimely death). Subsequent editions expanded on the original, including new poems that have since been recognized as Baudelaire’s masterpieces, producing a body of work that stands as the most consequential, controversial, and influential book of poetry from the nineteenth century.
