Symbolism was a late 19th-century art movement of French and Belgian origin in poetry and other arts seeking to represent absolute truths symbolically through language and metaphorical images, mainly as a reaction against naturalism and realism.

Fin de siècle is a French term meaning "end of century,” a phrase which typically encompasses both the meaning of the similar English idiom "turn of the century" and also makes reference to the closing of one era and onset of another. Without context, the term is typically used to refer to the end of the 19th century. This period was widely thought to be a period of social degeneracy, but at the same time a period of hope for a new beginning. The "spirit" of fin de siècle often refers to the cultural hallmarks that were recognized as prominent in the 1880s and 1890s, including ennui, cynicism, pessimism, and "a widespread belief that civilization leads to decadence."
