The Industrial Revolution, which emerged in Britain in the 18th century, was a major event that significantly influenced the course of human history. Lapar, Mantoux, and Ueda Teijiro all mentioned that Marx and Engels used or systematically explained the term "Industrial Revolution". However, these references were brief and lacked in-depth analysis, leaving room for further exploration and elaboration. Based on original works and returning to the texts, Marx and Engels analyzed and elucidated the five key factors that triggered the Industrial Revolution from the perspective of the contradiction between productive forces and relations of production. They presented the relationships between the subjects involved in these factors and, from the standpoint of the proletariat and with human emancipation as the guiding principle, revealed the institutional roots of alienated labor. They also analyzed and clarified the historical mission of the proletariat and the historical value of the Industrial Revolution, providing a valuable intellectual legacy and meaningful historical insights for understanding and grasping the ongoing new wave of the Industrial Revolution.
