What happened
The Tang dynasty, founded in 618 CE after the short-lived Sui collapsed, made Chang'an (modern Xi'an) into one of the largest cities in the world, with a population estimated around one million alongside a second capital at Luoyang. Both cities were, in the words of the Smithsonian's National Museum of Asian Art, flooded with foreigners from different parts of the world, and this confident cosmopolitanism shows up across Tang-era art. Alongside China's own Buddhism, Daoism, and Confucianism, the Tang court also tolerated newly arrived faiths: Manichaeism, brought from Iran by followers of Mani; Zoroastrianism, Iran's older traditional religion; and Christianity carried by Nestorian communities from Syria, commemorated in a stone monument raised in 781 CE and rediscovered in Shaanxi province in 1625.
Why it matters
Tolerating multiple foreign religions alongside its own, rather than suppressing them, made Tang China a hub where the trans-Eurasian exchange the Silk Road had opened centuries earlier kept moving goods, religious ideas, and people in both directions. The city's scale and diversity also gave Tang court culture, poetry, painting, and religious art, a wider range of influences to draw from than any earlier Chinese capital.
How we know
Tang-era administrative records and the 781 CE Nestorian stone monument document the presence of foreign religious communities directly; the population estimate for Chang'an comes from Tang census records analyzed by modern historians.
