Post-World War I refers to the period following the end of World War I in 1918, characterized by significant social, political, and artistic changes. This era saw a reaction against traditional norms and a rise in avant-garde movements as artists sought to express the disillusionment and trauma caused by the war. In this context, art became a medium for exploring new ideas and feelings, leading to the emergence of styles like German Expressionism and groups such as Die Brรผcke, which focused on individual experience and emotional depth.
