Chang'an, located in China's Shaanxi Province, was the capital city of several Chinese dynasties, including the Western Han and the Tang, from 202 BC to 907 AD. At various times, it was the largest city in the world. Its name was subsequently changed, and during the Ming dynasty period its modern name of Xi'an was adopted. The site of Chang'an south of the Wei River in central Xi'an has been inhabited since Neolithic times, when the Yangshao culture had a major center at Banpo to its south during the 5th millennium BC. Fenghao, the twin capitals of the Western Zhou, straddled the Feng River to its southwest from the 11th to 8th centuries BC and the state of Qin and its imperial dynasty had their capital in nearby Xianyang, north of the Wei, in the 4th and 3rd centuries BC. The First Emperor's mausoleum and its Terracotta Army lay to its east. Liu Bang moved his court to the Changle Palace in 200 BC, soon after the establishment of the Western Han. It held a central position in the large but easily defended Guanzhong Region, near but outside the ruins of the Qin Xianyang and Epang Palaces. Han Chang'an grew up to the north of it and the adjacent Weiyang Palace. Weiyang continued to serve as the imperial palace of the Xin, late Eastern Han, Western Jin, Han-Zhao, Former Qin, Later Qin, Western Wei, Northern Zhou, and early Sui dynasties and became the largest palace ever built, covering 4.8 km2 (1,200 acres)—nearly seven times larger than the Forbidden City—before its destruction under the early Tang. The main areas of Sui and Tang-era Chang'an was south of the earlier settlement and southeast of Weiyang. Around 750 AD, Chang'an was called a "million-man city" in Chinese records; most modern estimates put the population within the walls of the Tang city at around 800,000–1,000,000. The 742 AD census recorded in the New Book of Tang listed the population of Jingzhao, the province including the capital and its metropolitan area, as 1,960,188 people in 362,921 households and modern scholars—including Charles Benn and Patricia Ebrey—have concurred that Chang'an and its immediate hinterland could have supported around 2,000,000 people.
