1926年夏，當北伐軍總司令蔣介石率軍從廣東進入兩湖以來，其軍事和政治地位均受到嚴峻挑戰，處境艱難。其轉而率大軍由兩湖轉戰江西，卻由此開啟了走向權力巔峰之門。北伐軍佔領江西後，蔣介石將其總司令行營常駐南昌，以江西為發展基地，採取了種種措施以積蓄自身的力量。其通過構建江西的政治體系、穩定江西社會經濟秩序、大力宣傳三民主義，加強了對江西的控制。進而整頓軍事，研定下一步的軍事計畫，遙控指揮北伐大局，將其軍事勢力由江西一省而席捲東南五省。駐贛期間，蔣介石與日本和江浙財團的代表不斷接觸，初步結盟，加強了其與蘇俄和共產黨分裂的決心。蔣介石還努力爭取中央大員，力圖獲得黨內最大的支持。蔣介石駐紮江西的半年時光，是其積蓄實力，走向全國的開始。

Since the Northern Expedition force led by the commander-in-chief Chiang Kai-Shek came to Hunan and Hubei from Guangdong in 1926 summer, its military and political status was seriously challenged which put it in harsh situation. Thus the force headed for Jiangxi province, which also opened the door of its heading for overwhelming power. After occupying Jiangxi province, Chiang Kai-Shek located the headquarters of the Northern Expedition force in Nanchang city, made Jiangxi the developing basis, and took various measures to strengthen his power. By establishing the political system, stabilizing the social and economic order in Jiangxi, and preaching the Three Principles of the People, he consolidated his control of Jiangxi. Furthermore, he renovated the force, worked out the following military programs, commanded the overall Northern Expedition from afar, and enlarged his military power from Jiangxi to including the five provinces in southeast China. During stationing in Jiangxi, Chiang Kai-Shek kept contacting the delegates from both Japan and wealthy lords in Jiangsu and Zhejiang province, thus beginning forming an alignment with them and enhancing his resolution to break up with Soviet Russia and Chinese Communist Party. He also aimed to enlist the firmest support of senior officials and his own party. Therefore, half year of stationing of Chiang kai-shek’s troops in Jiangxi province had witnessed his strengthening power and the beginning of his later national dominance.
