Modernism
Modernism is a cultural and artistic movement that began in the late 19th and early 20th centuries, emphasizing experimentation, abstraction, and subjective experience in literature, visual arts, and music. It's a style and ideology that is the result of the Modern era.
It centers around beliefs in a growing alienation from prevailing morality, optimism, and convention, and seeks to change how human beings in a society interact and live together.
