Definition of Decadent movement

In 19th century European and especially French literature, decadence was the name given, first by hostile critics, and then triumphantly adopted by some writers themselves, to a number of late nineteenth century fin de siècle writers who were associated with Symbolism or the Aesthetic movement and who relished artifice over the earlier Romantics' naïve view of nature (see Rousseau). Some of these writers were influenced by the tradition of the Gothic novel and by the poetry and fiction of Edgar Allan Poe.
