The realist manifesto refers to a declaration that outlines the principles and intentions of the literary movement known as realism, which emerged in the late 19th century. This movement sought to depict everyday life and ordinary people with an emphasis on truth and accuracy, moving away from romanticism and idealism. The manifesto serves as a guide for writers to focus on social issues, character complexity, and realistic settings, highlighting the importance of portraying life as it truly is rather than how it could be imagined.
