1928 Who fought with whom in the Great Revolution? Why did it break out?

If you mean 1928 China Northern Expedition, please look down.

1928 was the last year of the Northern Expedition of the National Revolution, and it was a war between the National Government and China Beiyang Warlords. The National Revolutionary Army destroyed and controlled most of the northern warlords.

The reasons for the outbreak are complicated:

1 China was a divided country at that time, and the warlords needed a powerful regime to unify (everyone thought it was their own), so the war broke out.

The Northern Expedition is the only way for Sun Yat-sen, the father of our country, to formulate a plan to unify China and make China strong. Without the Northern Expedition, China could not be unified, let alone strong.

The Japanese waited for an opportunity in the Northeast, although Zhang reluctantly resisted and deceived the Japanese by virtue of his superb political means (on the one hand, he signed a treaty favorable to Japan in exchange for military and economic support, on the other hand, he used unofficial means to offset the benefits of Japanese treaties, such as Japan's immigration to the Northeast, and the Japanese became the main ethnic group in the Northeast, while Zhang immigrated from Shanhaiguan, and the Japanese were still a minority). If China is not reunified as soon as possible, divided China cannot resist Japan. Just look at the unified but corrupt Southern Song Dynasty, where the capital failed immediately after being broken for so many years, and the rapid demise of all Han forces after the capital was broken for so many years in the Ming and Qing Dynasties.

Failure: militarily, the Northern Expedition was a complete success. The National Revolutionary Army wiped out most of the northern warlords' troops, making it impossible to continue the rebellion and had to obey the orders of the National Government.

However, from our current political point of view, if the Northern Expedition failed, the first premise of the Northern Expedition was the cooperation between countries, not the unification of China or the elimination of warlords. Once the cooperation broke down and the Northern Expedition failed (see the history books of China people), the National Government 1928 broke away from China, then no matter how the military victory came from our current politics.
