蜀汉政权的发展历程与三大内部势力的分野
The Development Course of the Shu Han Regime and the Division of the Three Major Internal Forces

蜀汉的历史记载虽相对较少，但一直是学术界研究的热点。刘备起兵于涿郡，从北方到南方，足迹遍布幽、徐、豫、荆、益等州郡。他在不同的时期所招募的臣下，根据其加入蜀汉政权的地区与时间的不同，后形成了三大势力，即荆州势力、东州势力与巴蜀势力。三大势力的明争暗斗对蜀汉政权产生了两方面影响，一方面促进了刘备入蜀的进程，另一方面也使得蜀汉政权在中后期陷入了严重的内耗。
Although there are relatively few historical records of Shu Han regime, it has always been a hot topic of academic research. Liu Bei rose up in County Zhuo, from the north to the south, with his footprints spread throughout counties such as You Zhou, Xu Zhou, Yu Zhou , Jing Zhou, and Yi Zhou. The subjects he recruited at different times formed three interest groups based on the regions and times he joined the Shu Han regime, namely the Jingzhou Force, Dongzhou Force, and Bashu Force. The overt and covert struggles of the three forces had two impacts on the Shu Han regime. On the one hand, they promoted the process of Liu Bei’s entry into Shu, and on the other hand, they also caused serious internal friction for the Shu Han regime in the middle and later stages.
