Sharp angles, strange forms, lurid colors, and distorted perspectives are classic hallmarks of Expressionism, the twentieth century movement that prioritized emotion over objective reality. Though particularly present in Germany and Austria, the movement's approach flourished internationally and is today hailed as one of the most influential shifts in art history. Covering the group's stylistic tendencies, influences, and most important protagonists, this introductory book explores the Expressionist panorama of moods, ideas, and emotions and their abiding quest for deep authenticity.
