Modernism emerged in response to major social, political, and intellectual changes in the late 19th and early 20th centuries. These included the loss of religious belief, rise of science and technology, growth of mass culture, and changing gender roles. Major influences included Darwin, Marx, Freud, and Einstein. The generation that came of age during World War 1 felt disconnected from traditional values and sought new ways to find meaning. Modernist works emphasize individual perspectives and subjective experiences over rational order. They use experimental styles and indirect techniques to challenge social conformity. A key modernist theme is the quest for personal artistic ordering in a world seen as unstable and alienating.
