Modernism is an early 20th-century movement in literature, visual arts and music, that emphasized experimentation, abstraction and subjective experience. Philosophy, politics and social issues were also aspects of the movement which sought to change how 'human beings in a society interact and live together'. The modernist movement emerged during the late 19th century in response to significant changes in Western culture, including secularization and the growing influence of science. It is characterized as a rejection of tradition and a hunt for newer, more original means of cultural expression. Modernism was influenced by widespread technological innovation, industrialization and urbanization, as well as cultural and geopolitical shifts that occurred after World War I. Artistic movements and techniques associated with modernism include abstract art, stream of consciousness in literature, cinematic montage, atonal and twelve-tone music and modernist architecture and urban planning.

An art movement is a tendency or style in art with a specific art philosophy or goal, followed by a group of artists during a specific period of time, or, at least, with the heyday of the movement defined within a number of years. Art movements were especially important in modern art, when each consecutive movement was considered a new avant-garde movement. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality. By the end of the 19th century many artists felt a need to create a new style which would encompass the fundamental changes taking place in technology, science and philosophy.
