# Chang'an

34°18′30″N 108°51′30″E﻿ / ﻿34.30833°N 108.85833°E﻿ / 34.30833; 108.85833
Chang'an ( ; traditional Chinese: 長安; simplified Chinese: 长安; pinyin: Cháng'ān) is the traditional name of Xi'an and was the capital of several Chinese dynasties, ranging from 202 BCE to 907 CE. The site has been inhabited since Neolithic times, during which the Yangshao culture was established in Banpo, in what is now the city's suburbs. Furthermore, in the northern vicinity of modern Xi'an, Qin Shi Huang of the Qin dynasty, China's first emperor, held his imperial court and constructed his massive mausoleum guarded by the Terracotta Army.
From its capital at Xianyang, the Qin dynasty ruled a larger area than either of the preceding dynasties. The imperial city of Chang'an during the Han dynasty was located northwest of today's Xi'an. During the Tang dynasty, the area that came to be known as Chang'an included the area inside the Ming Xi'an fortification, plus some small areas to its east and west, and a substantial part of its southern suburbs. Thus, Tang Chang'an was eight times the size of the Ming Xi'an, which was reconstructed upon the site of the former imperial quarters of the Sui and Tang city. During its heyday, Chang'an was one of the largest and most populous cities in the world. Around AD 750, Chang'an was called a "million-man city" in Chinese records, with modern estimates putting it at around 800,000–1,000,000 within city walls. According to the census in 742 recorded in the New Book of Tang, 362,921 families with 1,960,188 persons were counted in Jingzhao Fu (京兆府), the metropolitan area including small cities in the vicinity.

## Peoples and Ethnicities

Two of the largest ethnic groups in Chang'an were Han Chinese and Sogdians (people from Sogdia). Their cultures and traditions at times overlapped and combined. For instance, there were tombs within the city in Chinese style, had Chinese writing, led to an underground compartment, and had descriptions of the deceased. They also had Sogdian elements such as a miniature stone house and a stone bedlike platform. Funeral beds tend to also depict a Sogdian swirl as well. There were also many motifs that involved things like bird priests, winged, crowned horsed, winged musicians, and crowned human figures with streamers behind them. These motifs are not fully known as not much is known of the Sogdian religion.
Ease of travel from the Yellow River and Yangtze River also made it easier for other travelers to go to Chang'an and sell goods to the people of the city. Some of these people even stayed and lived in the city as well. Chang'an would be an overlap for travelers going to other parts of the region. People from India, the Arabian Peninsula, Iranian plateau, and Eastern African Coast would have people traveling to there and people from there traveling and residing in Chang'an.
Not every government official took a liking to foreigners coming and staying into Chang'an. For instance, Yuan Zhen wrote about how non-Chinese people were "barbaric" and how their cultures and practices would degrade the Chinese way of life.

## Religious institutions

Immigrants brought the ideas of new religions into the capital. The hub-status of the city caused these religions to stick and grow over time. Evidence suggests at least five or six Zoroastrian temples existed inside of the city while four temples existed around the Western Market. Christianity was around at this time as well. It was brought by a man named Aluoben who was sent by a church official in Seleucia-Ctesiphon [Modern day Iran]. The Church of the East first settlement was in China circa 635. Several hundred stone tablets and an artifact related to the Church of the East were discovered, which pointed to the existence of an affiliated single Christian church. The Church of the East is a Christian organization which sponsored the creation of churches in multiple Chinese cities, like Chang’an. Members of the Church of the East had received support from the Tang dynasty and yet during this same dynasty, the emperor placed a ban on Buddhism and Christianity, and only Buddhism survived. In 843 the Tang emperor also banned the religion of Manichaeism. A few years later the emperor banned Zoroastrianism and reinstated the ban on Buddhism. This ban on Buddhism was lifted a short while later when the current emperor passed away.

## Han period

The Han capital was located 3 km northwest of modern Xi'an. As the capital of the Western Han, it was the political, economic and cultural center of China. It was also the eastern terminus of the Silk Road, and a cosmopolitan metropolis. It was a consumer city, a city whose existence was not primarily predicated upon manufacturing and trade, but rather boasted such a large population because of its role as the political and military center of China. By 2 AD, the population was 246,200 in 80,000 households. This population consisted mostly of the scholar gentry class whose education was being sponsored by their wealthy aristocratic families. In addition to these civil servants there was a larger underclass to serve them.
Initially, Emperor Liu Bang decided to build his capital at the area south of Luo River, which according to Chinese geography was in modern Luoyang. This location was the site of the holy city Chengzhou, capital of Eastern Zhou. However, the strategic military value of a capital located in the Wei Valley became the deciding factor for locating the new capital. To this end, it is recorded c 200 BC he forcibly relocated thousands of clans in the military aristocracy to this region. The purpose was twofold. First, it kept all potential rivals close to the new Emperor, and second, it allowed him to redirect their energy toward defending the capital from invasion by the nearby Xiongnu. His adviser Liu Jing described this plan as weakening the root while strengthening the branch.
After the necessary political structure was set up, the area of the capital was divided into three prefectures and construction began. At its founding in 195 BC, the population of Changan was 146,000. During the reign of Emperor Wu of Han, the diplomat Zhang Qian was dispatched westward into Central Asia. Subsequently, Chang'an city became the Asian gateway to Europe as the point of departure of the Silk Road. On 4 October 23 AD, Chang'an was captured and sacked during a peasant rebellion. The emperor, Wang Mang was killed and decapitated by the rebels two days later. After the Western Han period, the Eastern Han government settled on Luoyang as the new capital. Chang'an was therefore also sometimes referred to as the Western Capital or Xijing (西京) in some Han dynasty texts. In 190 AD during late Eastern Han, the court was seized and relocated back to Chang'an by the notorious Prime Minister Dong Zhuo, as it was a strategically superior site against the mounting insurgency formed against him. After Dong's death (192) the capital was moved back to Luoyang in August 196, and to Xuchang in autumn 196. By this time, Chang'an was already regarded as the symbolic site of supreme power and governance.

### City walls

The 25.7 km long city wall was initially 3.5 m wide at the base tapering upward 8 m for a top width of 2 m. Beyond this wall, a 6.13 m wide moat with a depth of 4.62 m was spanned by 13.86 m long stone bridges. The wall was later expanded to 12–16 m at base and 12 m high. The moat was expanded to 8 m wide and 3 m deep. The expansion of the wall was likely a solution to flooding from the Wei River. The entire city was sited below the 400 m contour line which the Tang dynasty used to mark the edge of the floodplain.
Twelve gates with three gateways each, according with the ritual formulas of Zhou dynasty urban planning, pierced the wall. These gates were distributed three a side and from them eight 45 m wide main avenues extended into the city. These avenues were also divided into three lanes aligned with the three gateways of each gate. The lanes were separated by median strips planted with pine, elm, and scholar trees. Bachengmen Avenue was an exception with a width of 82 m and no medians. Four of the gates opened directly into the palaces.

### City structure

The overall form of the city was an irregular rectangle. The ideal square of the city had been twisted into the form of the Big Dipper for astrological reasons, and also to follow the bank of the Wei River. The eight avenues divided the city into nine districts. These nine main districts were subdivided into 160 walled 1×1 li wards. About 50–100 families lived in each ward. Historically, Chang'an grew in four phases: the first from 200 to 195 BC when the palaces were built; the second 195–180 BC when the outer city walls were built; the third between 141 and 87 BC with a peak at 100 BC; and the fourth from 1 BC–24 AD when it was destroyed.
The Xuanpingmen gate was the main gate between the city and the suburbs. The district north of the Weiyang Palace was the most exclusive. The main market, called the Nine Markets, was the eastern economic terminus of the Silk Road. Access to the market was from the Northeast and Northwest gates, which were the most heavily used by the common people. The former connect with a bridge over the Wei River to the northern suburbs and the latter connected with the rest of China to the east. An intricate network of underground passages connected the imperial harem with other palaces and the city. These passages were controlled by underground gatehouses and their existence was unknown.

#### First phase

In 200 BC after marking the boundaries of the three prefectures, which comprised the metropolitan region of Xianyang, Liu Bang appointed Xiao He to design and build the new capital. He chose to site the city on ruins of the Qin dynasty Apex Temple (formerly, Xin Palace). This old Qin palace was meant to be the earthly mirror of Polaris, the apex star, where the heavenly emperor resided. This site thus represented the center of the earth lying under the center of heaven with an axis mundi running upward from the imperial throne to its heavenly counterpart. The ruins were greatly expanded to 7×7 li in size and renamed Changle Palace (长乐宫; 長樂宮; Chánglègōng). Two years later, a new palace called Weiyang Palace (未央宮; Wèiyānggōng) was constructed 5×7 li. Prime minister Xiao He convinced Liu Bang that both the excessive size and multiplicity of palaces was necessary to secure his rule by creating a spectacle of power.

#### Second phase

In 195 BC, his son, Emperor Hui of Han began the construction of the walls of Chang'an and finished them in September 191 BC. The grid north of the palaces was built at this time with a 2° difference in alignment to the grid of the palaces. The city remained quite static after this expansion.

#### Third phase

Emperor Wu began a third phase of construction which peaked on 100 BC with the construction of many new palaces. He also added the nine temples complex south of the city, and built the park. In 120 BC, Shanglin Park, which had been used for agriculture by the common people since Liu Bang was sealed off, was turned into an imperial park again. In the center of the park was a recreation of the three fairy islands in Kunming Lake.

### Palaces

* Changle Palace (长乐宫; 長樂宮; Chánglègōng) Also called the East Palace. It was built atop the ruins of Qin dynasty Apex Temple (Xingōng). After Liu Bang it was used as the residence of the Empress Regent. The 10,000 m wall surrounded a square 6 km$^2$ complex. Important halls of the palace included: Linhua Hall, Changxin Hall, Changqiu Hall, Yongshou Hall, Shenxian Hall, Yongchang Hall, and the Bell Room.
* Weiyang Palace (未央宮; Wèiyāng Gōng) Also known as the West Palace. The official center of government from Emperor Huidi onwards. The palace was a walled rectangle 2250×2150 m enclosing a 5 km$^2$ building complex of 40 halls. There were four gates in the wall facing a cardinal direction. The east gate was used only by nobility and the north one only by commoners. The palace was sited along the highest portion of the ridgeline on which Chang'an was built. In, fact the Front Hall at the center of the palace was built atop the exact highest point of the ridge. The foundation terrace of this massive building is 350×200×15 m. Other important halls are: Xuanshi Hall, Wenshi Hall, Qingliang Hall, Qilin Hall, Jinhua Hall, and Chengming Hall. Used by seven dynasties this palace has become the most famous in Chinese history.
* Gui Palace (桂宫; Guigōng) Built as an extension of the harem built in 100 BC

## Jin, Sixteen Kingdoms and Northern Dynasties period

Chang'an was briefly the capital of the Western Jin dynasty from 312 to 316. It was also the capital of Former Zhao (318–329), Former Qin (351–385) and Later Qin (384–417). In 417, a century after the Western Jin lost Chang'an, the city was reconquered by Liu Yu of Eastern Jin, who founded the Liu Song dynasty in 420. The city was lost to Northern Wei by 439. When Northern Wei split in two, Chang'an became the capital of Western Wei (535–557), and also of its successor state Northern Zhou (557–581).

## Sui and Tang periods

The Sui and Tang empires occupied the same location. In 582, Emperor Wen of the Sui dynasty sited a new region southeast of the much ruined Han dynasty Chang'an to build his new capital, which he called Daxing (大興; 'Great prosperity'). Daxing was renamed Chang'an in the year 618 when the Duke of Tang, Li Yuan, proclaimed himself the Emperor Gaozu of Tang. Chang'an during the Tang dynasty (618–907) was, along with Constantinople (Istanbul) and Baghdad, one of the largest cities in the world. It was a cosmopolitan urban center with considerable foreign populations from other parts of Asia and beyond. This new Chang'an was laid out on a north–south axis in a grid pattern, dividing the enclosure into 108 wards and featuring two large marketplaces, in the east and west respectively. Every day, administrators of the two marketplaces would beat gongs three hundred times in the morning and evening to signify the start and stop of business. People who lived in the wards were not allowed to go outside after curfew. Officials with higher ranking had the privilege to live closer to the central avenue. Chang'an's layout influenced the city planning of several other Asian capitals for many years to come. Chang'an's walled and gated wards were much larger than conventional city blocks seen in modern cities, as the smallest ward had a surface area of 68 acres, and the largest ward had a surface area of 233 acres (0.94 km$^2$). The height of the walls enclosing each ward were on average 9 to 10 ft (3.0 m) in height. The Japanese built their ancient capitals, Heijō-kyō (today's Nara) and later Heian-kyō or Kyoto, modeled after Chang'an in a more modest scale, yet was never fortified. The modern Kyoto still retains some characteristics of Sui-Tang Chang'an. Similarly, the Korean Silla dynasty modeled their capital of Gyeongju after the Chinese capital. Sanggyeong, one of the five capitals of the state of Balhae, was also laid out like Chang'an.

### Layout of the city

During Tang, the main exterior walls of Chang'an rose 18 ft (5.5 m) high, were 5 mi (8.0 km) by six miles in length, and formed a city in a rectangular shape, with an inner surface area of 30 sq mi (78 km$^2$). The areas to the north that jutted out like appendages from the main wall were the West Park, the smaller East Park, and the Daming Palace, while the southeasternmost extremity of the main wall was built around the Serpentine River Park that jutted out as well. The West Park walled off and connected to the West Palace (guarded behind the main exterior wall) by three gates in the north, the walled-off enclosure of the Daming Palace connected by three gates in the northeast, the walled-off East Park led in by one gate in the northeast, and the Serpentine River Park in the southeast was simply walled off by the main exterior wall, and open without gated enclosures facing the southeasternmost city blocks. There was a Forbidden Park to the northwest outside of the city, where there was a cherry orchard, a Pear Garden, a vineyard, and fields for playing popular sports such as horse polo and cuju (ancient Chinese football). On the northwest section of the main outer wall there were three gates leading out to the Forbidden Park, three gates along the western section of the main outer wall, three gates along the southern section of the main outer wall, and three gates along the eastern section of the main outer wall.
Although the city had many different streets and roads passing between the wards, city blocks, and buildings, there were distinct major roads (lined up with the nine gates of the western, southern, and eastern walls of the city) that were much wider avenues than the others. There were six of these major roads that divided the city into nine distinct gridded sectors (listed below by cardinal direction). The narrowest of these streets were 82 ft (25 m) wide, those terminating at the gates of the outer walls being 328 ft (100 m) wide, and the largest of all, the Imperial Way that stretched from the central southern gate all the way to the Administrative City and West Palace in the north, was 492 ft (150 m) wide. Streets and roads of these widths allowed for efficient fire breaks in the city of Chang'an. For example, in 843, a large fire consumed 4,000 homes, warehouses, and other buildings in the East Market, yet the rest of the city was at a safe distance from the blaze (which was largely quarantined in East Central Chang'an). The citizens of Chang'an were also pleased with the government once the imperial court ordered the planting of fruit trees along all of the avenues of the city in 740.

### Pools, streams, and canals

Within the West Park was a running stream and within the walled enclosure of the West Palace were two running streams, one connecting three ponds and another connecting two ponds. The small East Park had a pond the size of those in the West Palace. The Daming Palace and the Xingqing Palace (along the eastern wall of the city) had small lakes to boast. The Serpentine River Park had a large lake within its bounds that was bigger than the latter two lakes combined, connected at the southern end by a river that ran under the main walls and out of the city.
There were five transport and sanitation canals running throughout the city, which had several water sources, and delivered water to city parks, gardens of the rich, and the grounds of the imperial palaces. The sources of water came from a stream running through the Forbidden Park and under the northern city wall, two running streams from outside the city in the south, a stream that fed into the pond of the walled East Park, which in turn fed into a canal that led to the inner city. These canal waterways in turn streamed water into the ponds of the West Palace; the lake in the Xingqing Palace connected two canals running through the city. The canals were also used to transport crucial goods throughout the city, such as charcoal and firewood in the winter.

## Citywide events
### New Year

The grandest of all festivals, and a seven-day holiday period for government officials. Civil officials, military officers, and foreign emissaries gathered first in the early hours of the morning to attend a levee, an occasion where omens, disasters, and blessings of the previous year would be reviewed, along with tribute of regional prefectures and foreign countries presented. It was also an opportunity for provincial governors to present their recommended candidates for the imperial examination. Although festival ceremonies in Chang'an were lavish, rural people in the countryside celebrated privately at home with their families in age old traditions, such as drinking a special wine, Killing Ghosts and Reviving Souls wine, that was believed to cure illnesses in the following year.

### Lantern Festival

A three-day festival held on the 14th, 15th, and 16th days of the first full moon. This was the only holiday where the government lifted its nightly curfew all across the city so that people could freely exit their wards and stroll about the main city streets to celebrate. Citizens attempted to outdo one another each year in the amount of lamps and the size of lamps they could erect in a grand display. By far the most prominent was the one in the year 713 erected at a gate in Chang'an by the recently abdicated Emperor Ruizong of Tang. His lantern wheel had a recorded height of 200 ft (61 m), the frame of which was draped in brocades and silk gauze, adorned with gold and jade jewelry, and when it had its total of some 50,000 oil cups lit the radiance of it could be seen for miles.

### Lustration

This one-day festival took place on the third day of the third moon (dubbed the "double-three"), and traditionally was meant to dispel evil and wash away defilement in a river with scented aromatic orchis plants. By the Tang era it had become a time of bawdy celebration, feasting, wine drinking, and writing poetry. The Tang court annually served up a special batch of deep fried pastries as dessert for the occasion, most likely served in the Serpentine River Park.

### Cold Food Festival

This solar-based holiday on April 5 (concurrent with the Qingming Festival) was named so because no fires were allowed to be lit for three days, hence no warmed or hot food. It was a time to respect one's ancestors by maintaining their tombs and offering sacrifices, while a picnic would be held later in the day. It was also a time for fun in outdoor activities, with amusement on swing sets, playing cuju football, horse polo, and tug of war. In the year 710, Emperor Zhongzong of Tang had his chief ministers, sons-in-law, and military officers engage in a game of tug of war, and purportedly laughed when the oldest ministers fell over. The imperial throne also presented porridge to officials, and even dyed chicken and duck eggs, similar to the practice on Easter in the Western world.

### Fifth Day of the Fifth Moon

This one-day holiday dubbed the Dragon Boat Festival was held in honor of an ancient Chinese statesman Qu Yuan (c. 340-278 BC) from the State of Chu. Ashamed that he could not save the dire affairs of his state or his king by offering good council, Qu Yuan leaped into a river and committed suicide; it was said that soon after many went out on the river in boats in a desperate attempt to rescue him if still alive. This act turned into a festive tradition of boarding a dragon boat to race against other oarsmen, and also to call out Qu's name, still in search of him. The type of food commonly eaten during the Tang period for this festival was either glutinous millet or rice wrapped in leaves and boiled.

### Seventh Night of the Seventh Moon

This was a one-day festival that was held in honor of the celestial love affair with deities associated with the star Altair (the male cow-herd deity) in the constellation Aquila and the star Vega (the female weaver maid deity) in the constellation Lyra. For this holiday, women prayed for the enhancement of their skills at sewing and weaving. In the early eighth century Tang servitors had erected a 100 ft (30 m) tall hall by knotting brocades to a bamboo frame and laid out fruits, ale, and roasts as offerings to the two stellar lovers. It was during this holiday that the emperor's concubines threaded polychrome thread into needles with nine eyes, while facing the Moon themselves (in a ritual called "praying for skill [in sewing and weaving]").

### Fifteenth Day of the Seventh Moon

This holiday was called All Saints' Feast, developing from the legend Mulian Rescues His Mother. in which the bodhisattva savior Mulian who had discovered his mother paying for her sinful ways while in purgatory filled with hungry ghosts. According to the tale, she starved there because any food that she put into her mouth would turn into charcoal. Then it was said that she told the Buddha to make an offering with his clergy on the fifteenth day of the seventh month, a virtuous act that would free seven generations of people from being hungry ghosts in Hell as well as people reborn as lower animals. After Mulian was able to save his own mother by offerings, Mulian convinced the Buddha to make the day into a permanent holiday. This holiday was an opportunity of Buddhist monasteries to flaunt their collected wealth and attract donors, especially by methods of drawing crowds with dramatic spectacles and performances.

### Fifteenth Day of the Eighth Moon

This festival (today simply called the Moon Festival or Mid-Autumn Festival), took place in mid autumn, and was designated as a three-day vacation for government officials. Unlike the previous holiday's association with Buddhism, this holiday was associated with Taoism, specifically Taoist alchemy. There was a tale about a hare on the moon who worked hard grinding ingredients for an elixir by using a mortar and pestle. In folklore, a magician escorted Emperor Illustrious August to the palace of the moon goddess across a silver bridge that was conjured up by him tossing his staff into the air. In the tale, on the fifteenth day of the eighth moon, the emperor viewed the performance of "Air of the Rainbow Robe and Feathered Skirt" by immortal maids. He memorized the music, and on his return to earth taught it to his performers. For people in Chang'an (and elsewhere), this holiday was a means for many to simply feast and drink for the night.

### Ninth Day of the Ninth Moon

This was a three-day holiday associated with the promotion of longevity (with chrysanthemum as the main symbol). It was a holiday where many sought to have picnics out in the country, especially in higher elevated areas such as mountain sides. Without the ability to travel away to far off mountains, inhabitants of Chang'an simply held their feasts at the tops of pagodas or in the Serpentine River Park. Stems and leaves of chrysanthemum were added to fermented grains and were brewed for a year straight. On the same festival the following year, it was believed that drinking this ale would prolong one's life.

### The Last Day of the Twelfth Moon

On this holiday ale and fruit were provided as offerings to the god of the stove, after having Buddhist or Taoist priests recite scripture at one's own home (if one had the wealth and means). Offerings were made to the stove god because it was his responsibility to make annual reports to heaven on the good deeds or sins committed by the family in question. A family would do everything to charm the god, including hanging a newly painted portrait of the god on a piece of paper above their stove on New Years, which hung in the same position for an entire year. It was a common practice to rub in some alcoholic beverage across the picture of the deities mouth, so that he would become drunk and far too inebriated to make any sort of reasonably bad or negative report about the family to heaven.

### Grand Carnivals

Carnivals during the Tang period were lively events, with great quantities of eating, drinking, street parades, and sideshow acts in tents. Carnivals had no fixed dates or customs, but were merely celebrations bestowed by the emperor in the case of his generosity or special circumstances such as great military victories, abundant harvests after a long drought or famine, sacrifices to gods, or the granting of grand amnesties. This type of carnival as a nationwide tradition was established long before the Tang by Qin Shihuang in the third century BC, upon his unification of China in 221. Between 628 and 758, the imperial throne bestowed a total of sixty nine different carnivals, seventeen of which were held under Empress Wu. These carnivals generally lasted 3 days, and sometimes five, seven, or nine days (using odd numbers due so that the number of days could correspond with beliefs in the cosmos). The carnival grounds were usually staged in the wide avenues of the city, and smaller parties in attendance in the open plazas of Buddhist monasteries. However, in 713, a carnival was held in the large avenue running east to west between the West Palace walls and the government compounds of the administrative city, an open space that was 0.75 mi (1.21 km) long and 1,447 ft (441 m) wide, and was more secure since the guard units of the city were placed nearby and could handle crowd control of trouble arose. Carnivals of the Tang dynasty featured large passing wagons with high poles were acrobats would climb and perform stunts for crowds. Large floats during the Tang, on great four-wheeled wagons, rose as high as five stories, called 'mountain carts' or 'drought boats'. These superstructure vehicles were draped in silken flags and cloths, with bamboo and other wooden type frames, foreign musicians dressed in rich fabrics sitting on the top playing music, and the whole cart drawn by oxen that were covered in tiger skins and outfitted to look like rhinoceroses and elephants. An official in charge of the Music Bureau in the early seventh century set to the task of composing the official music that was to be played in the grand carnival of the year. On some occasions the emperor granted prizes to those carnival performers he deemed to outshine the rest with their talents.

## Decline

In 682, a culmination of major droughts, floods, locust plagues, and epidemics, a widespread famine broke out in the dual Chinese capital cities of Chang'an and Luoyang. The scarcity of food drove the price of grain to unprecedented heights of inflation, while a once prosperous era under emperors Taizong and Gaozong ended on a sad note.
Much of Chang'an was destroyed during its repeated sacking during the An Lushan Rebellion and several subsequent events. Chang'an was occupied by the forces of An Lushan and Shi Siming, in 756; then taken back by the Tang government and allied troops in 757. In 763, Chang'an, modern-day Xian, was briefly occupied by the Tibetan Empire. In 765, Chang'an was besieged by an alliance of the Tibetan Empire and the Uyghur Khaganate. Several laws enforcing segregation of foreigners from Han Chinese were passed during the Tang dynasty. In 779, the Tang dynasty issued an edict which forced Uighurs in the capital, Chang'an, to wear their ethnic dress, stopped them from marrying Chinese females, and banned them from pretending to be Chinese. Between 783 and 784, Chang'an was again occupied by rebels during the Jingyuan Rebellion.
In 881, Chang'an was occupied by the rebel Huang Chao, who made it the seat of his Qi Dynasty. In 882, the Tang dynasty briefly regained control of Chang'an. However, the Tang forces, although welcomed by the inhabitants, looted Chang'an before being driven back by the forces of Huang Chao. In revenge, Huang Chao conducted a systematic slaughter of the inhabitants after retaking the city. Chang'an was finally retaken by the Tang government in 883. In 904, the warlord Zhu Quanzhong ordered the city's buildings demolished and the construction materials moved to Luoyang, which became the new capital. The residents, together with the emperor Zhaozong, were also forced to move to Luoyang. Chang'an never recovered after the apex of the Tang dynasty, but there are some monuments from the Tang era still standing.
After Zhu Quanzhong moved the capital to Luoyang, the Youguo Governorate (佑國軍) was established in Chang'an, with Han Jian being the jiedushi (佑國軍節度使). Han Jian rebuilt Chang'an on the basis of the old Imperial City. Much of Chang'an was abandoned and the rebuilt Chang'an, called "Xincheng (lit. new city)" by the contemporary people, was less than 1/16 of the old Chang'an in area. The rest of the city was overrun by nature and was used for agriculture. Then the northern and eastern city wall was expanded a little and the official name of the city was changed from Jingzhao, which means capital city, to Xi'an in Ming dynasty.

## Archaeological Finds

Two Sogdian tombs were discovered in the early 2000s near Chang'an (modern day Xi'an). They were the first Sogdian tombs discovered which had never been opened before their discovery by archaeologists, which meant that the artifacts inside the tombs were well preserved. The tombs are evidence of the cultural interconnections between immigrants and Chinese cultural practices which they adopted when they moved to large population centers like Chang'an.

### An Jia Tomb

The tomb of An Jia was discovered in 2001 and had mixed elements of Chinese and Sogdian burial practices. An Jia's remains were buried in an uncommon manner as his bones were discovered strewn throughout the tomb which was uncommon to both the Confucian and Zoroastrian customs at the time. Archaeologists also uncovered an epitaph to An Jia written in the Chinese language which retells his life, career, and achievements as a "Sabao of the Tong Prefecture and Commander General of the Great Zhou Dynasty".

### Shi Wirkak Tomb

The tomb of Shi Wirkak was discovered in 2003-2004 slightly over 1 mile East of An Jia's tomb. Similarly to An Jia's tomb it also had the mix of both the Chinese and Sogdian burial practices. However, unlike An Jia the there were two versions of Shi Wirkak epitaph in Chinese and Sogdian, though they were not the direct translations of each other which in quality of text could mean that the scribe who wrote the epitaphs had little understanding of either language.
