The “Niu–Li Factional Strife,” named after Niu Sengru (779–847) and Li Deyu (787–850), is an enduring theme in Tang history. Based on accounts of personal animosity, a narrative evolved in which Niu and Li have become the ringleaders of two factions that drew in almost all high-profile literati of the ninth century. This article revises traditional and modern narratives of the Strife by first showing that the scattered and contradictory evidence in the earliest sources does not bear out the model of a decades-long struggle between two factions. Second, it demonstrates how “Niu and Li” first arose as an emblem of Tang weakness and a rallying cry for unity within the bureaucracy under the Northern Song two centuries later. Finally, it shows how modern historians picked up the loose ends and remoulded them into a struggle between different classes against the backdrop of factious politics in Republican China.

Tang expansion in the early seventh century brought about a series of changes to the eastern Tianshan region, including the incorporation of the region into the imperial postal relay and defence system. Important structures, including cities for the soldiers and other immigrants from Tang territory, along with fortresses and relay posts, were established along the major routes in the region, especially on the northern slopes of the Tianshan range. However, the era after the decline of the Tang is not as well known, due to a lack of contemporary sources. This article, based on a comprehensive analysis of documentary and unearthed materials, discusses a previously unacknowledged process of urbanisation in the region during the Uighur era. Uighur immigrants, originally nomads on the Mongolian steppe, occupied not only the cities, but also the garrisons and other infrastructure established by the Tang. As a result, urban settlements were established at sites that had previously served military purposes. Clusters of new cities emerged in the region, especially on the northern slopes of the Tianshan, which had long been part of the nomadic cultural zone. The sedentary and mercantile culture of the Uighurs played an important role in this process, serving as an impetus for economic prosperity along the eastern section of the Silk Road between the Tang and Mongol–Yuan eras.

The Tang period (618–907) stands out as one of the most important chapters of the history of early Inner Asia, where bilateral diplomatic interactions on the Chinese – Inner Asian frontier reached a high point. Since its establishment, the Tang pursued close relations with the neighboring Türk Qaghanate and various other Turkic and Mongolic speaking groups in the Inner Asian steppes. These relations, sometimes friendly, other times hostile, were to a great extent recorded in the official histories, a genre of historical writing that was systematized with the establishment of Historiography Office at the Tang court. As political texts written with particular agendas, official histories present certain limitations. Recent archaeological research in both China and Inner Asia provide a different line of evidence for the study of diplomatic relations between China and Inner Asia. This paper aims to discuss the history of Pugu, a Turkic speaking Inner Asian group who had submitted to the Tang in the seventh century, through an analysis of the tomb inscription of Pugu Yitu, then leader of the Pugu, and an army general and court official of the Tang.

Du Fu, one of the two most celebrated poets of the Tang, was very much a product of his era in the way that he found a usable past in Han-dynasty verse, episodes, and people. From 750 on, his writings were replete with allusions to the Han, some subtle and others more forthright. Taken together, these allusions suggest his firm beliefs in the course of history determined by human moral agency, in morality as “a man's own charge”; also in the role of fate determining the succession of dynasties, even as he deplored the workings of capricious fate on individual lives. Such beliefs are unremarkable in content, being much closer to conventional Tang concepts of the individual than most commentaries on Du Fu allow.
