This paper examines the background of the implementation of the People’s Republic of China(PRC), which is not revealed in previous studies. Before and after the establishment of the PRC, we looked at the reasons why the Chinese Communist Party(CCP) actively promoted the Chinese government and what was the goal to be achieved through the Chinese government. In this paper, it was “war” that was noted while looking at the process of establishing the PRC. I think the nature of the political party implemented by the PRC before and after the establishment of the PRC is different. From the establishment of the CCP in July 1921 to the establishment of the PRC on October 1st, 1949, the CCP had been threatened and fought by the The Kuomintang(KMT). Prior to the founding of the PRC, the goal was to win the competition with the CCP by promoting the expansion of the Chinese Red Army through the veterans policy. Immediately after the victory in the Chinese Civil War and the founding of the PRC, the resolution of the economic difficulties and stability of the national system were prioritized. However, due to the “The Korean War” that broke out on June 25th, 1950, the establishment of national politics was accelerated. The long-term goal of the veterans policy, which was enacted and implemented after the founding of the country, was to contribute to the solidarity and stability of the national system.
