Geographical Setting and Climate
The Ancient City of Gaochang is situated approximately 40 kilometers west of Turpan City, in Erbao Township, Gaochang District, Xinjiang Uyghur Autonomous Region, China. The site occupies a substantial area of about 2.2 million square meters. Its geographical context is characterized by a low-lying terrain surrounded by mountains, creating a basin-like environment.
Climate
Gaochang experiences a temperate continental climate. This climate type is defined by significant temperature variations between summer and winter. Furthermore, the region is characterized by persistent aridity and minimal rainfall, making it a challenging environment for settlement and agriculture. The dry conditions, however, have contributed significantly to the preservation of the ancient city's ruins.
Historical Overview: A Timeline of Gaochang
Gaochang's history spans approximately 1,400 years, from the 1st century BC to the 14th century AD. It served as the central town of the Turpan Basin throughout this extensive period, witnessing various ruling powers and cultural shifts. The city's evolution can be broadly categorized into the following key historical periods:
Early Period: Western Han and Gaochang Commandery
The initial phase saw the establishment of Gaochang Wall during the Western Han Dynasty (206 BC – 9 AD). The area was of strategic value due to its location and access to oases. It developed in to the Gaochang Commandery.
Gaochang Kingdom
Following the decline of Han influence, Gaochang emerged as an independent kingdom. This period marked a significant era of local rule and cultural development.
Tang Dynasty's Western Prefecture (Xizhou)
The Tang Dynasty (618-907 AD) reasserted Chinese control over the region, incorporating Gaochang as Xizhou, or the Western Prefecture. This era witnessed increased cultural exchange and integration with the Tang empire.
Gaochang Uyghur Period
After the decline of the Tang Dynasty, the Uyghurs, a Turkic group, established their control over the region, leading to the Gaochang Uyghur period. This period saw the continuation of cultural blending and the flourishing of Manichaeism and Buddhism.
The Uyghur Kingdom of Qocho
The Uyghur kingdom, sometimes referred to as Uyghuristan, was situated in the Tarim Basin. It's important to consider its broader influence. The Uyghurs were originally part of a tribal confederation, the Tiele, in Northern China. They later formed a powerful empire. After their empire was defeated by the Kyrgyz in 840, many Uyghurs fled south to the Tarim Basin, including the area around Gaochang and Turpan.
The Uyghurs established the Kingdom of Qocho (also known as the Gaochang Uyghur Kingdom) in this new territory. This kingdom was a vibrant center of culture and trade, known for its religious tolerance and artistic achievements. It became a significant center of Buddhism, but also included Manichaean and Nestorian Christian communities.
Abandonment
Gaochang was ultimately abandoned at the end of the 13th century due to warfare during the late Yuan and early Ming Dynasties. The conflicts and instability of this period led to the city's decline and eventual desertion. Most of its structures disappeared over time, leaving behind the ruins visible today.
City Layout and Architecture
The Ancient City of Gaochang exhibits a distinctive urban layout, reflecting its strategic importance and the social organization of its inhabitants. The city is structured in three concentric layers:
The Outer City
The outermost layer, encompassing the largest area, likely served as the primary residential and commercial zone. It would have housed the majority of the city's population, along with markets, workshops, and other essential facilities.
The Inner City
Enclosed within the outer city, the inner city probably contained more important administrative and religious buildings. This area may have housed the residences of higher-ranking officials and wealthier citizens.
The Palace City (Khan's Fortress)
The innermost layer, also known as the Khan's Fortress or "Kehan Fort," is located in the northernmost part of the city. This fortified area served as the royal residence and the center of political power. It is an irregular square shape and represents the most protected and exclusive section of Gaochang.
Architectural Details and Materials
Although much of Gaochang's architecture has been lost to time, the surviving ruins reveal insights into the construction techniques and materials used. Rammed earth was a predominant building material, reflecting the local environment and available resources. This technique involved compacting layers of earth to create sturdy walls and foundations. Some structures may have incorporated wooden elements, though these have largely decayed over the centuries. The use of bricks, particularly in religious buildings, is also evident.
Religious Sites
Within the city, particularly in the southwest and southeast corners of the outer city, are the remains of two well-preserved temple sites. These temples provide valuable evidence of the religious diversity of Gaochang. The presence of both Manichaean and Buddhist murals, statues, and other artifacts indicates that these religions coexisted and flourished within the city. This religious pluralism is a significant aspect of Gaochang's cultural heritage.
Manichaeism in Gaochang
Manichaeism, a religion founded by the prophet Mani in the 3rd century AD, spread widely along the Silk Road. Gaochang became a significant center for Manichaeism, particularly during the Uyghur period. The religion combined elements of Zoroastrianism, Christianity, and Buddhism, emphasizing a dualistic cosmology of good versus evil. The discovery of Manichaean texts and art at Gaochang has provided invaluable insights into this now-extinct religion.
Buddhism in Gaochang
Buddhism, originating in India, also spread along the Silk Road and took root in Gaochang. The city became an important center for Buddhist learning and practice, with numerous monasteries and temples constructed. Buddhist scriptures, art, and other artifacts found at Gaochang testify to the religion's significant influence on the city's culture.
The Silk Road played a crucial role in the transmission of Buddhism from India to China and other parts of East Asia. Gaochang, as a major hub along this route, served as a vital conduit for the exchange of Buddhist ideas, texts, and practices.
