Expressionism emphasizes the emotional aspect of the human character. It is in stark contrast to impressionist artwork, where accuracy and subject matter are at the core. Rather than conveying objectivity of the subject matter, Expressionist artists use the canvas for emotional interpretation.
Expressionism goes against centuries of artistic tradition and empowers contemporary artists to let go of their emotions and depict them with unusual imagery. It evolved in the early part of the 20th century when artists sought to connect with the future via unique compositions, colours, and forms.
