Abstract: The history of the CPC's ideological and political education has the dual attributes of Marxist theory and history. In-depth research will help to elevate the understanding of the regularity of ideological and political education, further enhance the academic discourse power of ideological and political education, and strengthen the academic consensus of the history of ideological and political education. History is not simply a vertical extension of time, but also a horizontal expansion of space. In-depth research on the history of the CPC's ideological and political education requires grasping four pairs of important relationships in three dimensions on the basis of mastering its basic context and development clues: grasping the relationship between internal history and external history at the macro level; grasping the relationship between history and theory, truth-seeking in history writing and practical application of historiography at the meso level; grasping the relationship between detail research and overall research at the micro level. This will promote the study of the CPC's ideological and political history from general history to specialized history, from historical narrative to historical speculation, and from theoretical spontaneity to theoretical consciousness.
