Expressionism as an artistic movement developed in the early 20th century, a period in which new and influential explorations of psychology and human behavior were taking place. Artists began to look at the world more subjectively, often distorting its depictions to achieve an emotional effect in artworks that still hold a power to move and challenge viewers. Art historian Joseph Paul Cassar traces the movement’s roots, meaning, influences, and most notable practitioners. (World Art History Certificate core course, 1 credit)
