"Therefore one of the first major internal causes that led to the creation of a suitable environment for the Cultural Revolution was the historical demand for a national sense of unity and popular cohesion around a national identity. At the beginning of the century, the Monarchy had indeed a legitimate power over its subjects, yet it offered a limited amount of unity, due to the administrative organization of the state. Thus, the different provinces that made up imperial China ware tight together not so much by the sense of belonging to common cultural roots, but rather by the administrative and political connections that governed the administration. Thus, it was only natural for frictions between China and its neighbors to be a constant reality during that time. In this sense, the Sino-Japanese War is a proper example for pointing out the constant simmering geopolitical situation in the area. World War II was one of the occasions which proved the need for the Chinese people to form a united and uniform national identity that would stand up against any possible future conquering forces. Therefore, an external factor determined the openness of the population for discussions related to nationality and unity. .

             Another element that proved decisive for the evolution of the political system in China, especially following the First World War and the social evolution that marked the end of the war for the Russian side, was the communist influence. In general, the communist doctrine stands for unity against a common enemy that, as Marx identified it to be, was the liberal bourgeoisie. Indeed, the Russian revolution represented an important model to be followed by many nations around the world, reason for which many countries, including the US became aware of and reluctant to any communist initiative or symbolism. In this sense, the internal factor, the need to find a proper substitute for a political regime that would cater for the demands of the population, intermingled with an external one, the international influence of communism.
