Abstract: The writing of the Critique of Hegel's Philosophy of Right is a very complex process, and its relation to the writing of the Kreuznach Notebooks is not only a documentary issue but also a theoretical issue still being debated in the international academic community. From the viewpoint of literature, scholars such as Rabin, Taubert, Rumiantsyeva, and Jäckel have engaged in heated discussions regarding possible interruption(s) the writing once experienced, the sequence and chronology of the Kreuznach Notebooks, and the temporal relationship between the two works, and they have arrived at differing conclusions with historical and textual evidence. Theoretically, the historical studies in the Kreuznach Notebooks serve as crucial sources for Marx's shift toward materialist thought and an examination of the relationship between these two texts thus sheds light on the methodological origins and concrete process of Marx's first materialist transformation. When both philological and theoretical dimensions are considered together, it becomes evident that the writing likely underwent two interruptions and during the intervals, Marx partially excerpted the Kreuznach Notebooks. His sustained engagement with historical studies gradually led him to abandon the attempt to invert Hegel's philosophy of right from a juridical standpoint and ultimately to set aside the manuscript of the Critique of Hegel's Philosophy of Right altogether.
