The word decadence, which at first meant simply "decline" in an abstract sense, is now most often used to refer to a perceived decay in standards, morals, dignity, religious faith, or skill at governing among the members of the elite of a very large social structure, such as an empire or nation state. By extension, it may refer to a decline in art, literature, science, technology, and work ethics, or (very loosely) to self-indulgent behaviour.
