Realism was a general movement in 19th-century theatre that developed a set of dramatic and theatrical conventions with the aim of bringing a greater fidelity of real life to texts and performances. It shared many stylistic choices with naturalism, including a focus on everyday (middle-class) drama, colloquial speech, and mundane settings. Realism and naturalism diverge chiefly on the degree of choice that characters have: while naturalism believes in the overall strength of external forces over internal decisions, realism asserts the power of the individual to choose (see A Doll's House).
Russia's first professional playwright, Aleksey Pisemsky, and Leo Tolstoy (The Power of Darkness (1886)), began a tradition of psychological realism in Russia which culminated with the establishment of the Moscow Art Theatre by Constantin Stanislavski and Vladimir Nemirovich-Danchenko. Their ground-breaking productions of the plays of Anton Chekhov in turn influenced Maxim Gorky and Mikhail Bulgakov. Stanislavski went on to develop his 'system', a form of actor training that is particularly suited to psychological realism.
19th-century realism is closely connected to the development of modern drama, which, as Martin Harrison explains, "is usually said to have begun in the early 1870s" with the "middle-period" work of the Norwegian dramatist Henrik Ibsen. Ibsen's realistic drama in prose has been "enormously influential."
In opera, verismo refers to a post-Romantic Italian tradition that sought incorporate the naturalism of Émile Zola and Henrik Ibsen. It included realistic – sometimes sordid or violent – depictions of contemporary everyday life, especially the life of the lower classes.
