There are many possible answers to this question because the creation of novels involves many different fields and eras.

Enlightenment ideologists proposed many new literary theories, advocating rationality, science, and critical thinking. These theories contributed to the development and prosperity of the novel. One of the earliest modern novels was Daniel Defoe's Crusoe. The development of modern novels was also influenced by the cultural movements of the 20th century, such as romanticism, realism, realism, and so on. Among them, the most famous were the Russian works "Crime and Punishment" and "War and Peace", which had a profound impact on the development of modern novels.
