The development of modern literature can be traced back to the late 19th century, when many political, social, and cultural changes took place, which had a profound impact on literature. 1. Scientific and technological progress: With the development of the industrial revolution, the advancement of science and technology has promoted the innovation of literary forms and contents. For example, the novel first appeared in the manuscripts of craftsmen, and then gradually developed into printed matter and gradually became popular. 2. The rise of democratic ideas: In the late 19th century, the rise of democratic ideas led to higher and higher demands on the political system. The influence of this ideology was also reflected in many works of literature, such as freedom and human rights, which also became propaganda for democratic ideas. 3. Prominent social problems: At the end of the 19th century, social problems such as the gap between the rich and the poor, class division, colonial problems, etc. became increasingly prominent. These problems prompted them to hope to reveal and solve these problems through literature. 4. The prosperity of literary schools: From the end of the 19th century to the beginning of the 20th century, many literary schools emerged, such as realism, romanticism, symbolism, modernism, etc. These literary schools expressed different views and thoughts on life, society and human destiny in different social backgrounds. 5. Transformation of literary criticism: With the rise of the New Culture Movement, literary criticism began to transform and pay more attention to the analysis and interpretation of literary works. This method of criticism not only promoted the development of literary research, but also promoted the spread and acceptance of literary works. These are the background and influencing factors of the development of modern literature. These changes and influences have also laid the foundation for the development of modern literature.
