Realism (theatre) in the context of "Eugene O'Neill"

A wide range of movements existed in the theatrical culture of Europe and the United States in the 19th century. In the West, they include Romanticism, melodrama, the well-made plays of Scribe and Sardou, the farces of Feydeau, the problem plays of Naturalism and Realism, Wagner's operatic Gesamtkunstwerk, Gilbert and Sullivan's plays and operas, Wilde's drawing-room comedies, Symbolism, and proto-Expressionism in the late works of August Strindberg and Henrik Ibsen.

Twentieth-century theatre describes a period of great change within the theatrical culture of the 20th century, mainly in Europe and North America. There was a widespread challenge to long-established rules surrounding theatrical representation; resulting in the development of many new forms of theatre, including modernism, expressionism, impressionism, political theatre and other forms of Experimental theatre, as well as the continuing development of already established theatrical forms like naturalism and realism.

Throughout the century, the artistic reputation of theatre improved after being derided throughout the 19th century. However, the growth of other media, especially film, has resulted in a diminished role within the culture at large. In light of this change, theatrical artists have been forced to seek new ways to engage with society. The various answers offered in response to this have prompted the transformations that make up its modern history.

A soliloquy (/səˈlɪl.ə.kwi, soʊˈlɪl.oʊ-/, from Latin solus 'alone' and loqui 'to speak', pl. soliloquies) is a speech in drama in which a character speaks their thoughts aloud, typically while alone on stage. It serves to reveal the character's inner feelings, motivations, or plans directly to the audience, providing information that would not otherwise be accessible through dialogue with other characters. They are used as a narrative device to deepen character development, advance the plot, and offer the audience a clearer understanding of the psychological or emotional state of the speaker. Soliloquies are distinguished from monologues by their introspective nature and by the absence or disregard of other characters on the stage.

The soliloquy became especially prominent during the Elizabethan and Jacobean periods, when playwrights used it as a means to explore complex human emotions and ethical dilemmas. William Shakespeare employed soliloquies extensively in his plays, using them to convey pivotal moments of decision, doubt, or revelation. Notable examples include Hamlet's "To be, or not to be" speech, which reflects on life and death, and Macbeth's contemplation of the consequences of regicide. Although the use of soliloquy declined in later theatrical traditions with the rise of realism, it has continued to appear in various forms across different genres, including film and television.

The fourth wall is a performance convention in which an invisible, imaginary wall separates the actors from the audience. While the audience can see through this "wall", the convention assumes that the actors behave as if they cannot. From the 16th century onward, the rise of illusionism in staging practices—culminating in the realism and naturalism of the theatre of the 19th–century—led to the development of the fourth wall concept.

The metaphor relates to the mise-en-scène behind a proscenium arch. When a scene is set indoors and three of the room's walls are depicted onstage—forming what is known as a box set—the "fourth" wall lies along the line (technically called the proscenium) dividing the stage from the auditorium, effectively where the audience sits. However, the fourth wall is a theatrical convention, not a feature of set design. Actors ignore the audience, focus entirely on the fictional world of the play, and maintain immersion in a state that theatre practitioner Konstantin Stanislavski called "public solitude" —the ability to behave privately while being observed, or to be "alone in public." This convention applies regardless of the physical set, theatre building, or actors' proximity to the audience. In practice, actors often respond subtly to audience reactions, adjusting timing—particularly for comedic moments—to ensure lines are heard clearly despite laughter.

Georg Morris Cohen Brandes (4 February 1842 – 19 February 1927) was a Danish critic and scholar who greatly influenced Scandinavian and European literature from the 1870s through the turn of the 20th century. He is seen as the theorist behind the "Modern Breakthrough" of Scandinavian culture. At the age of 30, Brandes formulated the principles of a new realism and naturalism, condemning hyper-aesthetic writing and also fantasy in literature. His literary goals were shared by some other authors, among them the Norwegian "realist" playwright Henrik Ibsen.

When Georg Brandes held a series of lectures in 1871 with the title "Main Currents in 19th-century Literature", he defined the Modern Breakthrough and started the movement that would become Cultural Radicalism. In 1884 Viggo Hørup, Georg Brandes, and his brother Edvard Brandes started the daily newspaper Politiken with the motto: "The paper of greater enlightenment". The paper and their political debates led to a split of the liberal party Venstre in 1905 and created the new party Det Radikale Venstre.
