The unification of China marked the history in Chin Dynasty and China was continued to be ruled by the empire of Han Dynasty under one regime. But in late Eastern Han Dynasty, around the end of 2nd century to the middle of the 3rd century, the unified Mainland China gradually to decline and was in an era dominated by chaotic infighting between warlords. The Three Kingdoms period preceded and the Tsao- Wei, Shu-Han, and Sun-Wu kingdoms came to power in 221 A.D., which began a time of legendary generals and advisors, whose legacies in leaderships, politics, military strategies, and foreign affairs marked an important chapter in Chinese history.
This thesis is focused on the rise and fall of Shu-Han Kingdom and the author would like to estab-lish a system of historical and strategic analysis based on approaches of historical study, "Political Sys-tems Theory" by David Easton and "Total Strategy Theory" by Andre Beaufre.
The thesis is composed in four main categories: First is the analysis of both advantages and dis-advantages of unification and standardized China; and the natural disasters and man-made calamities led to a faster fall of Eastern Han Dynasty, which ushered the growth of The Three Kingdoms period. Second part is the historical study on the foundation of warlords at the time, and Liu Bei''s rise to power. Third, the study of Liu Bei and Chu-Ko Liang''s strategies to sustain the unification of the Eastern Han Empire before its fall and the growth of Shu-Han Kingdom. Lastly, the study of Shu-Han political and military strategies, and domestic policies. Most import of all, the reasons of failing to gain power and reunite China.
In the author''s opinions, the ultimate reason for the fall of Shu-Han Kingdom laid on the careless foreign policies to Sun-Wu Kingdom and the excessive military expeditions. The loss of the State of Yi was an irrecoverable consequence for the cause. If only Liu Bei had foreseen the problems a couple of years ago, the northward expeditions, followed his death, led by Chu-Ko Liang might have changed the history in China.
