Chang’an and Other Tang Cities: Wards, Markets and Communities

From 618 to 907 CE, Chang’an served as the Tang empire’s principal capital, except during the Wu Zhou interruption of 690–705. The city concentrated the court and central government, but it was also a place of residence, trade, religious activity and migration. Its planned wards and regulated markets shaped daily movement around the capital.

Other cities had different roles. Luoyang was the eastern capital and, under Wu Zetian, the centre of the Wu Zhou court. Yangzhou, at the meeting of the Yangtze River and the canal network, grew as a major port and trading centre. Together, these cities show how Tang urban life depended on both political institutions and regional connections.

A planned capital and its precincts

The Sui established a new capital, Daxing, on the site later occupied by Tang Chang’an; the Tang renamed it Chang’an in 618. Its planned street grid divided a walled area of about 78 square kilometres into large residential wards. Broad avenues connected the city gates and organized movement through the capital. More than a hundred wards made up the city, but their walls and gates distinguished them from the open street grid familiar in many modern cities.

Chang’an’s plan also separated the imperial court from the rest of the city. The Palace City housed the emperor and court, while a distinct Imperial City contained central government offices. The larger Outer City held residential wards, markets and religious institutions. This arrangement placed government near the palace while keeping much of the city’s commerce and residential life in separate districts.

The city had to support a very large population. Estimates for the walled capital around the mid-eighth century commonly fall between 800,000 and one million people. A census in 742 counted 1,960,188 people in 362,921 households across Jingzhao, the administrative area that included Chang’an and its surrounding territory.

Wards, supplies and daily movement

Wards enclosed clusters of residences and institutions behind gates. Officials regulated entry and movement, including night-time restrictions, while main avenues connected the gated districts with markets and government precincts. Residents consequently planned errands and visits around both distance and the times when routes were open.

Keeping such a large city supplied required transport and storage as well as local exchange. Canals ran through Chang’an, linking water sources and palace or park ponds. They also carried bulky goods, including firewood and charcoal. Grain was stored in government granaries for distribution, connecting the capital’s daily needs to public provisioning and transport networks. These systems helped support the court and urban population, but also made the city dependent on supplies from beyond its walls.

Markets and the regulation of trade

Chang’an’s East and West Markets were enclosed commercial districts with gates and internal divisions. Government offices in the markets supervised trade and transactions. Their shops and stalls offered food and drink, including tea, cooked cereals, pastries and wine, alongside goods such as iron tools and musical instruments. A deposit business in the West Market points to commercial services beyond the direct sale of goods.

Market activity followed an official timetable. Drums announced the opening around midday, and a gong signalled closing before dusk. The rules placed much formal commerce within supervised market precincts and the working day. Yet restrictions did not always determine what residents did: residential night markets continued to attract customers, despite an effort to close them in 841. The contrast between official hours and later trade shows how urban regulation could be contested in practice.

Religious institutions and migrant communities

Chang’an’s residents included people with different origins and religious affiliations. Sogdians, a people from Central Asia, were among the city’s established communities, and merchants and travellers connected the capital to wider Asian routes. Archaeological finds, including tombs with Chinese-language epitaphs and Chinese burial features alongside Sogdian imagery, show cultural forms meeting within the city. Such evidence suggests exchange and adaptation, rather than a simple division into separate populations.

Religious life also had a place in the urban fabric. Buddhist monasteries and Daoist institutions operated alongside Zoroastrian worship and a Church of the East Christian community attested in China from 635. These institutions could attract donors and hold substantial resources. In 713, Emperor Xuanzong ordered the dissolution of a prominent Buddhist monastery’s Inexhaustible Treasury, a fund built from anonymous donations. Its wealth was redistributed to other monasteries and Daoist abbeys and used for repairs to statues, halls and bridges. The episode shows that religious foundations could serve communities and accumulate wealth, while remaining subject to intervention by the court. In 843, the Tang court prohibited Manichaeism, another example of the changing limits placed on religious practice.

Government rules could also mark distinctions among groups. An edict of 779 required Uyghurs in Chang’an to wear their own dress and restricted intermarriage with Chinese women and the adoption of Chinese identity.

Luoyang and Yangzhou: different urban roles

Luoyang was Chang’an’s counterpart as the Tang eastern capital, not simply another version of the western capital. The Sui built a new city there in 605, and the Tang used it as an important court centre. During Wu Zetian’s Wu Zhou regime, Luoyang became her principal capital and was known as Shendu, or the Divine Capital. Its political role could therefore change with the location of the court, while Chang’an remained the main reference point for the Tang capital system.

Yangzhou developed around transport and trade rather than the presence of the imperial court. Located near the Yangtze and the canal routes linking north and south, it became a major Tang port for domestic and foreign commerce. Merchants from places including Persia, the Arab world and Korea lived there. The city also had workshops and craft production, including fine bronze mirrors. In 760, forces led by Tian Shengong entered and sacked Yangzhou during a local rebellion; thousands of Arab and Persian merchants were among those killed. The violence exposed the risks faced by trading communities as well as the city’s importance as a commercial centre.

Conflict and the changing capital

Chang’an’s position did not protect it from war or shifting frontier power. An Lushan’s forces occupied the capital in 756, before Tang forces and their allies retook it in 757. Tibetan forces briefly occupied the city in 763 and besieged it in 765. Rebels also held Chang’an during the Jingyuan uprising of 783–784. These episodes disrupted government and city life, and show that the capital’s security depended on political and military control beyond its walls.

Later rebellions brought further destruction. Huang Chao’s forces occupied Chang’an in 881, and the Tang court regained it in 883. In 904, as Tang rule approached its end, the warlord Zhu Wen ordered the destruction of much of the city and the forced relocation of its remaining population to Luoyang. The capital’s history was therefore not only one of planned districts and regulated commerce: it was also shaped by the shifting fortunes of the court, the army and the communities living within its walls.
