Expressionism:

A movement that began in Germany in about 1910 and is best typified by Georg Kaiser and Ernst Toller. Expressionist works display reality through the unique and often eerie perspective of an artist looking out on the world from the depths of the psyche. They are often a revelation of the artist's personal fears or agonies. (Expressionism reacted against Impressionism, which showed the effect of the world on the artist.) In Kaiser's Expressionist play From Morn to Midnight, the world appears only through the Cashier's inner reality.
