When did modern become popular?

Modernism began to gain popularity in the late 19th and early 20th centuries, particularly after World War I. It emerged as a response to industrialization, urbanization, and the disillusionment of the war, leading artists, architects, and writers to explore new forms and ideas. The movement reached its peak in the 1920s and 1930s, influencing various fields such as visual arts, literature, design, and architecture. Its legacy continues to impact contemporary culture.
