At the end of the nineteenth century, the perception of animals changed significantly due to the theory of evolution and other new ideas, which also affected a number of Dutch socialist-leaning writers. Utilizing the framework of literary animal studies, this article investigates how animals were represented in their works.

Herman Heijermans takes a more ambivalent position: some of his writings show the possibility of animal agency, whereas in others, animals are subordinate to people's needs and are objectified.
