Among the Chinese character epitaphs written for Sogds found to date, we find many instances of appointment to the post of commander of garrisons (junfu 軍府) under the garrison militia (fubing 府兵) system between the Northern Dynasties and early Tang periods. It is also a fact that Sogds were also involved in the formation of local militias that comprised the fighting units of the fubing system. From examples of such Sogdian involvement in military affairs, I had previously pointed out that Sogdian garrisons and army corps may be assumed to have existed at the time in question. However this is merely an assumption based on the existing epigraphy and research to date on the military institutions of the Northern Dynasties, Sui and Tang Periods, concluding that there is still no hard evidence establishing that fact, until now. That is to say, from the epitaph of Cao Yi, which was made public in 2011 in the city of Fenyang, Shanxi Province, we have evidence that a "chejifu 車騎府" of the regional garrison was set up under the "sabao 薩宝" of Jiezhou 介州during the early Tang Period, proving without a doubt the existence of a Sogdian garrison and army corps there. The garrison also joined the Taiyuan uprising led by Li Yuan 李淵in 617, and it had incorporated Sogdian armed forces since before the founding of the Tang. Moreover, when compared to the Sui period epitaph of Yu Hong 虞弘 excavated in 1999, we find that the Tang period garrison had its origins in the local army corps led by Sogdian commander Yu during the last years of the Northern Zhou, and it becomes clear that Sogdian garrisons and army corps existed in the final years of the Northern Dynasties at the latest. Then during the Zenguan 貞観 (627-49) era, as the Tang Dynasty established control, these Sogdian garrisons and army corps were disbanded. In consequence, Sogdian ruling class returned to their former occupations such as commerce, and others became peasants of the Tang Dynasty.

The Xuanwumen incident (玄武門の変) which occurred in A.D. 626 involved Prince Lishimin 李世民 killing his brother Jiancheng 建成, the crown prince of the Tang 唐 dynasty, and coercing his father Liyuan 李淵, the first emperor of the dynasty, to relinquish the throne. This incident is usually regarded as either sibling rivalry or a court dispute over the title of crown prince and has been considered to have had no influence on the political structure of the dynasty. Therefore, the recent research has not taken into consideration the concerned parties in the incident. For example, there were a number of natives of Shangdong 山東 among Lishimin's retainers, particularly natives of Qiji 斉済 (Qijun 斉郡 and Jibeijun 済北郡 of the Sui 隋 period). They had been affiliated with Limi 李密, a revolutionary at the end of the Sui period. After Limi's defeat, they came to serve the Tang dynasty under Lishimin. It was Fangxuanling 房玄齢 (the right hand man of Lishimin and the ringleader of the Xuanwumen incident) who organized this group under Lishimin. Fang was a member of the Qinghefang family (清河房氏), which had been influential in the Qiji area since the 460s and had continuously produced many regional officials of the Qiji area during the Sui period. Furthermore, Limi's right hand man was also of Fang's lineage. It can be said that the natives of the Qiji area who were once active under Limi formed a strong group supporting Lishimin under the direction of Fang.Meanwhile, Emperor Liyuan began to disperse Lishimin's group and organize his retainers into the Twelve Guanzhong Armies (関中十二軍) as a countermeasure against the Turks (突厥) in A.D. 625. It was a move to transfer the central force of the Tang dynasty from his second son's retinue to his own. The Xuanwumen incident broke out when antagonism between the emperor and his son reached a climax as the result of a collision between two disparate power bases.

中央アジア出身のソグド人のうち、北朝・隋・唐時代の中国社会で活動した者たちを取り上げ、彼らの政治・軍事・文化史上の活動を、いわゆる正史などの編纂史料のみならず、既出・新出の墓誌銘をはじめとする石刻史料および考古学的発見による文物資料を利用し、検証を加えた。その結果、ソグド人の東方活動には、北朝・隋・唐初における活動の担い手と、それ以降の時期の活動の担い手において、断絶があるのではないかという仮説にいたった。また、ソグド人研究に必要な基本的資料の収集をほぼ終え、別途公開する基礎的作業が完成した。
