In 618, the Tang dynasty took power and began rebuilding imperial control after earlier civil wars. Stronger government and security helped long-distance trade recover across the Silk Road network. Over time, the Tang capital at Chang’an became a major destination for people and goods arriving from Central Asia and beyond.
In 640, Tang forces conquered Gaochang (near today’s Turpan), a key oasis region on the Silk Road. This helped the Tang project power into the Tarim Basin, where caravan routes depended on protected water and pasture stops. Control of these oases supported both military supply lines and commercial travel.
Soon after Gaochang’s conquest, the Tang set up the Anxi Protectorate to manage the Western Regions. The protectorate system tied frontier defense to the movement of merchants, envoys, and tribute. It became a backbone of Tang influence along the northeastern Silk Road routes.
In 648, the Tang conquered Kucha and made it the main seat of the Anxi administration. This shift placed Tang authority closer to the key junctions that linked China with Central Asia. It also strengthened the chain of garrisons that protected trade through the Tarim Basin.
Between 648 and 658, the Tang installed major garrisons in Kucha, Khotan, Kashgar, and Karashahr. These bases helped stabilize the route system that caravans relied on, especially around desert crossings. Military support could deter raids, manage border tolls, and keep communications moving.
During the early and high Tang, Dunhuang’s Mogao Caves were expanded and painted with scenes reflecting travel and multicultural life. UNESCO notes that Tang-period caves include imagery and materials that document politics, economy, and daily life in western China. These sites show how Silk Road trade supported religious patronage and cultural mixing in frontier towns.
In 751, Tang forces fought the Abbasid Caliphate (with allies) at the Battle of Talas and were defeated. The battle is widely seen as marking the end of Tang attempts to expand further into Central Asia. While trade did not stop, the political balance along the western Silk Road shifted toward other powers.
From 755 to 763, the An Lushan Rebellion devastated Tang finances, administration, and internal security. The Tang court struggled to protect roads and supply lines, and the state’s grip on frontier regions weakened. These shocks made long-distance trade more dangerous and less predictable.
In late September 758, Arab and Persian raiders attacked Guangzhou, a major southern port linked to Indian Ocean trade. Accounts describe the city being plundered and warehouses burned before the attackers departed by sea. The event highlights that Tang “Silk Road” trade was not only overland—maritime routes were crucial and could be vulnerable to violence.
In 760, violence in the wealthy commercial city of Yangzhou led to the killing of thousands of foreign merchants, especially Arabs and Persians. The massacre occurred amid the instability of the An Lushan era. It illustrates how political disorder could turn cosmopolitan trading centers into targets for plunder and ethnic scapegoating.
In 781, a bilingual Chinese–Syriac monument (often called the Nestorian Stele) was erected in Chang’an. It describes the spread of Christianity in Tang China and notes official recognition tied to a mission arriving in 635. The stele is evidence that Chang’an’s cosmopolitan culture included not only foreign goods but also organized foreign religious communities.
After the rebellion began, Tang forces were drawn back from the Hexi Corridor, the narrow passage linking central China to the Western Regions. The Tibetan Empire gradually occupied the area, and Dunhuang fell to Tibetan forces in 786, with wider control following in the 790s. This cut or complicated key overland trade routes that had fed Tang-era Silk Road commerce.
From 841 to 845, Emperor Wuzong’s policies suppressed Buddhism and also targeted other religions seen as foreign, including Zoroastrianism, Manichaeism, and Christianity. Temples were closed and property was seized, reshaping the institutions that often supported travel, lodging, and cultural exchange. This period marked a clear tightening of Tang tolerance that had helped earlier cosmopolitan trade flourish.
After the Tibetan Empire weakened, a Dunhuang resident, Zhang Yichao, seized key towns from Tibetan control in 848. This led to the Tang-loyal Guiyi Circuit, which helped reconnect parts of the Hexi Corridor and revive regional movement of goods and people. The recovery was partial and fragile, but it shows how local powers tried to rebuild Silk Road traffic when the central state could not fully do so.
Around 850–851, the merchant Sulaymān al-Tājir is associated with accounts of travel to China, including observations about Guangzhou and Chinese products such as porcelain. Such writings show sustained long-distance commercial interest in Tang goods even after earlier turmoil. They also highlight how foreign merchants gathered and circulated practical information about markets and shipping routes.
In 879, the rebel Huang Chao occupied Guangzhou, a rich port city central to long-distance commerce. Britannica describes this southern push as part of a revolt that badly weakened Tang rule. The event signaled that even major trade centers could no longer rely on imperial protection.
In 878–879, forces associated with the Huang Chao upheaval carried out a massacre in Guangzhou that included large numbers of foreign residents and merchants, according to later reports. Although exact totals are debated, the episode is widely remembered as a severe blow to Guangzhou’s international merchant community. It reflects a broader late-Tang pattern: warfare and insecurity drove a sharp decline in the open, multicultural trade environment of earlier centuries.
Huang Chao died in July 884 after years of warfare that weakened the Tang state. Even after the rebellion ended, central control was badly damaged, and the dynasty moved toward collapse. This outcome marks a clear end point for the classic Tang-era “cosmopolitan” Silk Road moment: trade routes and cities remained, but the political conditions that supported wide-open exchange were no longer stable.
