For the Nanking Government, the period of 1928-1937 is that of "political tutelage". To propagate the ideology of the KMT and to stabilize its regime are among its most important works. This paper tries, at first, to find out the history of propaganda of the KMT, and the organization of its Propaganda Department; then, to see the politics, means, and objects of its propaganda. From the aspects of "unification of the country, elimination of warlords", "anti-Communists", "propagation of the ideology of the Three Principles", and "anti-imperialists", this paper tries to examine the ways and the results of the propaganda of the Nationalist Government in Nanking.
