The Tang Dynasty in 90 Minutes, Part 2: Chang'an, the Capital That Defined an Empire
The first guide covered the Tang dynasty's rise and major events. This second part focuses on Chang'an — the Tang capital, its grid plan, its population, its cosmopolitanism, and what survives today in modern Xi'an.
Tang Chang'an (长安) covered ~84 km², planned on a strict cardinal-aligned grid of ~108 walled residential and commercial wards (坊). Wards closed at night by gate curfew; markets — the East Market and the cosmopolitan West Market (西市) — were designated trading zones. The West Market was the Silk Road's eastern terminal, with Sogdian, Persian, Indian, and Arab merchants and legally recognised Nestorian, Zoroastrian, Islamic, and Manichaean communities.
At its 8th-century peak, Chang'an held ~1 million people within the walls, making it the largest city in the world. Byzantine Constantinople held ~300,000–400,000 at its height.
What survives in Xi'an: Giant Wild Goose Pagoda (大雁塔, 652 CE, still standing); Tang West Market Museum (大唐西市博物馆, above original West Market archaeological remains); Shaanxi History Museum (陕西历史博物馆, outstanding Tang artefact collection including tri-colour pottery). The city walls are largely Ming dynasty built on Tang foundations.
