The word realism is used in several of the liberal arts; particularly painting, literature, and philosophy. It is also used in international relations.
In the visual arts and literature, realism is a mid-19th century movement, which started in France. The realists sought to render everyday characters, situations, dilemmas, and events; all in an "accurate" (or realistic) manner. Realism began as a reaction to romanticism, in which subjects were treated idealistically. Realists tended to discard theatrical drama and classical forms of art to depict sometimes ugly or commonplace subjects, sometimes even a moral message.
The movement is anticipated by the work of the French author Stendhal, but the "father" of realism is generally thought to be Honoré de Balzac. His Comédie Humaine is a panoramic view of 19th-century France in over 70 novels. Gustave Flaubert clearly defined the movement with his brilliant novel of the bourgeois Madame Bovary. Balzac and especially Flaubert influenced to a high degree the later realists and naturalists: Guy de Maupassant, Joris Karl Huysmans, and, in England, George Eliot.
By 1890, many began to reject realism, thinking it too external and superficial. Modified versions, however, were employed by such authors as Thomas Hardy, who realistically presented extreme pessimism, and Henry James, who sought to understand his characters psychologically.
At the turn of the 20th century, realism as a dominant movement in France gave way to symbolism and neo-romanticism.

Confusingly, various philosophically unrelated positions, in some cases diametrically opposed ones, are termed "realism." In large measure this depends on which debates are active at the time, and may be encouraged by the fact that a philosophical position often looks stronger if you attach the word "real" to it.
The oldest use of the term comes from Medieval interpretations of Greek philosophy. Here "realism" is contrasted with "conceptualism" and "nominalism". This can be called "realism about universals." Universals are terms or properties that can be applied to many things, rather than denoting a single specific individual--for example, red, beauty, five, or dog, as opposed to Socrates or Athens. Realism holds that these universals really exist, independently and somehow prior to the world; it is associated with Plato. Conceptualism holds that they exist, but only insofar as they are instantiated in specific things; they do not exist separately. Nominalism holds that universals do not "exist" at all; they are no more than words we use to describe specific objects, they do not name anything. This particular dispute over realism is largely moot in contemporary philosophy, and has been for centuries.
In another sense realism is contrasted with idealism. In still a third, and very contemporary sense realism is contrasted with anti-realism.
Both these disputes are often carried out relative to some specific area: one might, for example, be a realist about physical matter but an anti-realist about ethics.
Increasingly these last disputes, too, are rejected as misleading, and some philosophers prefer to call the kind of realism espoused there "metaphyiscal realism," and eschew the whole debate in favour of simple "naturalism" or "natural realism", which is not so much a theory as the position that these debates are ill-conceived if not incoherent, and that there is no more to deciding what is really real than simply taking our words at face value.

Closely linked to realism in philosophy, is realism in research. Realist researchers believe that since they are attempting to describe the real world they have to be cautious about how the do so. Typically realists use qualitative research methods. In this sense, realism is opposed to positivism, which tends towards quantitative method.
A style of composition or singing which attempts to imitate the accents of natural speech. Used by 19th century Russian composer, Modest Mussorgsky.

A degree of similitude of the simulation to the real world. Most gamers and developers attach great importance to the increasing realism of games. This notion is sometimes attacked by a minority of gamers, who argue that developers do not spend enough time and resources on improving the gameplay.
