Xi’an was once one of the largest cities on Earth
Around 750, the city now called Xi’an was Chang’an: a “million-man city” at the eastern end of the Silk Road, home to Persians, Sogdians, Arabs and Christian monks.

Xi’an means “Western Peace”, a name given in the Ming dynasty. For most of its history, the city was called Chang’an: “Perpetual Peace”.
A capital for a thousand years
Chang’an was the capital of several dynasties, including the Western Han and the Tang, between 202 BC and 907 AD. Chinese tradition often counts thirteen dynasties that ruled from the area, depending on how you count.
A million people
Around 750, Chinese records called Tang Chang’an a “million-man city”. Modern estimates put the population inside its walls at 800,000 to 1,000,000, with perhaps two million in the wider area. Along with Constantinople and Baghdad, it was one of the largest cities in the world.
The Tang city was laid out on a strict grid of walled wards, with two great markets:
- the East Market, for Chinese goods and crafts;
- the West Market, the Silk Road bazaar, where Persian and Central Asian merchants sold horses, jewels, glass and spices.
A cosmopolitan capital
At the eastern end of the overland Silk Road, Chang’an drew Sogdians, Persians, Arabs, Indians and monks of the Church of the East, Christians who reached China in the 7th century. Buddhism, Zoroastrianism, Manichaeism, Christianity and Islam all had communities there.
Many of them stayed. Their descendants are part of why Xi’an still has a large Muslim Quarter today.
