Although Chiang Kai-shek was the president of The President of the Republic of China, he was the president of the Chinese Nationalist Party. Regrettably, however, until Chiang Kai-shek came to Taiwan in 1949 as the "island owner", he did not actually unify China. Chiang Kai-shek was elevated to the chairmanship of the Central Committee of the Kuomintang and the chairman of the Military Commission in 1928. In April of that year, he formed four group armies with Feng Yuxiang, Yan Xishan, and Li Zongren to march north, defeated the Feng warlord Zhang Zuolin, and ended the rule of the Beiyang warlords. In October, he was appointed chairman of the Nationalist Government and commander-in-chief of the army, navy, and air force, and Zhang Xueliang's affiliation changed banners, and Chiang Kai-shek nominally unified the whole country and reorganized the Nationalist Government. But at this time, China under the rule of the Kuomintang was still full of factions, and there were countless warlords, large and small. Chiang Kai-shek was also known in the United States as the chairman of the national government of the five provinces (that is, the Jiangsu, Zhejiang, and Shanghai generation controlled by Chiang Kai-shek), although Chiang Kai-shek was later annexed and eliminated several times, but the Gui and Yan factions accompanied Chiang Kai-shek until the end.
The factions of Chiang Kai-shek's military group, other bigwigs said in their answers in great detail and clearly, the great supremacy is the central system and the local system, and then the central system has the Whampoa system and the local system that took refuge in the early days, the local system such as Yan Xishan, the Jin Sui Army, the Gui system of Li and Bai, which everyone is familiar with, and there are many other remote areas of the Yunnan Army, Ma Jiajun, Xinjiang Shengshi Talent Department, etc.
In fact, the factional context of Chiang Kai-shek's military group has always been very clear, such as the subdivision of the Whampoa system and the Chen Cheng civil engineering system, Hu Zongnan, Tang Enbo, and Du Luming's respective hills, but in the end they are all Whampoa forces that Chiang Kai-shek can rely on.
The local factions in the north are dominated by the Northwest Army derived from the Northwest Army, Yan Xishan, Han Fuqu, Song Zheyuan, Ji Hongchang, Shi Yousan, Zhu Huaibing, Sun Lianzhong, and Yang Hucheng, Zhang Zizhong, Wu Wenhua, Fu Zuoyi, etc., who are slightly younger, and I don't know how Mr. Feng played a good card in his hand into this virtue. Chiang Kai-shek's southern warlords were subdued by the Red Army's Long March, and all kinds of coercion were roughly subdued, and to the north, they were subdued by the anti-Japanese resistance.
Chiang Kai-shek's defeat has always been emphasized as a political defeat, and militarily, given the domestic situation in China at that time, there was no one or several local systems that could compete with Chiang Kai-shek. Therefore, these military bloc factions were not the fundamental reason for Chiang Kai-shek's eventual defeat.
If you want to say that the factions of Yu Shandu, Chen Lie, Huang Yong, and Xu Hui who pose a threat to Chiang Kai-shek, there is actually one: Deng Yanda's third party! Regarding Deng Yanda, now we give a very high historical evaluation, but mainly to say that he was the anti-Chiang historical exploits of the Kuomintang left, in fact, in those years, Deng Yanda's third party was the most dangerous enemy of both the Kuomintang and the Communist Party, and our party's Mr. Runzhi started as a peasant movement, and finally relied on a spark to set the prairie on fire, and the countryside surrounded the city to succeed, but this set of theories was learned and explored when he was working with Deng Yanda's subordinates, and later Deng Yanda formed a third party, which overlapped with the coverage of our party. Therefore, even after April 12, the third party is more dangerous than the Kuomintang, but this topic will not be extended here.
Regarding Chiang Kai-shek, Deng Yanda's attitude has always been to oppose it, Chiang Kai-shek's biggest enemy in his life, Chiang Kai-shek himself clearly said that it was Deng Yanda and not the Communist Party, why? It is still a problem of overlapping market coverage in terms of competition, and the core of Chiang Kai-shek's military and political affairs is the Whampoa department, and the Whampoa system, including the split between the Kuomintang and the Communist Party, is not as big as the split of the Whampoa Revolutionary Alumni Association organized by Deng Yanda. The Whampoa Alumni Association formed by Deng Yanda was directly aimed at opposing Chiang, and it is said that it brought together more than 5,000 students.
In 31 years, Chiang Kai-shek trapped Deng Yanda in Shanghai, and three or four months later, Deng Yanda was shot under great pressure, and more than 20 people who were the first offender of the Huangpu Alumni Association were also escorted to Nanjing for reprimands.
And Yu Shandu is the second phase, he is actually the leader, and he is also the first to give in after Nanjing's admonition, but in the third or third year, it is said that he was corrupt and degenerated to use military channels to sell drugs, and was personally ordered to be shot by Chiang Kai-shek. I have always opposed conspiracy theories, but this matter, I have always felt foggy, these four alumni union cadres all have the identity of our party, and in the end, only Xu Huizhi followed him to Taiwan, and was shot to death with the crime of common espionage in 51, so Yu Shandu's death is not so simple.
This class reunion organized by Deng Yanda, if Jiang Xianyun had not sacrificed, this position would have been Jiang Xianyun's, and that influence would be even more terrifying, Jiang Xianyun was gone, Yu Shandu could actually appear as a second-phase identity, at that age, he could participate in the fight of the gods, of course, he had a considerable talent. Chiang Kai-shek doesn't say anything else, he really has nothing to say to his classmates in Whampoa, Zhang Lingfu can be suppressed for killing his wife, and Yu Shandu is still a matter of drug trafficking? (Selling big tobacco in those days and drug trafficking now are really not the same nature), so Yu Shandu's death was mostly because of the class reunion, and he snatched food from the principal's bowl!
