Usage of the term frequently implies moral censure, or an acceptance of the idea, met with throughout the world since ancient times, that such declines are objectively observable and that they inevitably precede the destruction of the society in question; for this reason, modern historians use it with caution. The word originated in Medieval Latin (dēcadentia), appeared in 16th-century French, and entered English soon afterwards. It bore the neutral meaning of decay, decrease, or decline until the late 19th century, when the influence of new theories of social degeneration contributed to its modern meaning.
In literature, the Decadent movement—late nineteenth century fin de siècle writers who were associated with Symbolism or the Aesthetic movement—was first given its name by hostile critics. Later it was triumphantly adopted by some of the writers themselves. The Decadents praised artifice over nature and sophistication over simplicity, defying contemporary discourses of decline by embracing subjects and styles that their critics considered morbid and over-refined. Some of these writers were influenced by the tradition of the Gothic novel and by the poetry and fiction of Edgar Allan Poe.
Decadence was the name given to a number of late nineteenth-century writers who valued artifice over the earlier Romantics' naïve view of nature. Some of them triumphantly adopted the name, referring to themselves as Decadents. For the most part, they were influenced by the tradition of the Gothic novel and by the poetry and fiction of Edgar Allan Poe, and were associated with Symbolism and/or Aestheticism.
This concept of decadence dates from the eighteenth century, especially from Montesquieu, and was taken up by critics as a term of abuse after Désiré Nisard used it against Victor Hugo and Romanticism in general. A later generation of Romantics, such as Théophile Gautier and Charles Baudelaire took the word as a badge of pride, as a sign of their rejection of what they saw as banal "progress." In the 1880s a group of French writers referred to themselves as Decadents. The classic novel from this group is Joris-Karl Huysmans' Against Nature, often seen as the first great decadent work, though others attribute this honor to Baudelaire's works.
In Britain and Ireland the leading figure associated with the Decadent movement was Irish writer, Oscar Wilde. Other significant figures include Arthur Symons, Aubrey Beardsley and Ernest Dowson.
