Abstract: "politics and war" is the core proposition of war concept in Huai Nan Zi, whose fundamental principle is that the success and failure of war is determined by politics. The basic strategy is that politics is governed by morality and justice while military is controlled by politics, which reflects the historical fusion of Taoism, Confucianism and Legalism. This concept of war features a combination of politics and military and a reflection on the high politicization of war, which develops the thought of military school in pre-Qin Dynasties.
