Sichuan United Work Front

Sichuan (; zh, c=, labels=no, ; zh, p=Sìchuān; alternatively romanized as Szechuan or Szechwan; formerly also referred to as "West China" or "Western China" by Protestant missions) is a province in Southwest China occupying most of the Sichuan Basin and the easternmost part of the Tibetan Plateau between the Jinsha River on the west, the Daba Mountains in the north and the Yungui Plateau to the south. Sichuan's capital city is Chengdu. The population of Sichuan stands at 83 million. Sichuan neighbors Qinghai to the northwest, Gansu to the north, Shaanxi to the northeast, Chongqing to the east, Guizhou to the southeast, Yunnan to the south, and the Tibet Autonomous Region to the west.

In antiquity, Sichuan was the home of the ancient states of Ba and Shu. Their conquest by Qin strengthened it and paved the way for Qin Shi Huang's unification of China under the Qin dynasty. During the Three Kingdoms era, Liu Bei's state of Shu was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhong's rebellion and the area's subsequent Manchu conquest, but recovered to become one of China's most productive areas by the 19th century. During World War II, Chongqing served as the temporary capital of the Republic of China, making it the focus of the Japanese bombing. It was one of the last mainland areas captured by the People's Liberation Army during the Chinese Civil War and was divided into four parts from 1949 to 1952, with Chongqing restored two years later. It suffered gravely during the Great Chinese Famine of 1959–61 but remained China's most populous province until Chongqing Municipality was again separated from it in 1997.

The Han Chinese people of Sichuan speak distinctive Sichuanese dialects of Mandarin Chinese. The spicy Sichuan pepper is prominent in modern Sichuan cuisine, featuring dishes—including Kung Pao chicken and mapo tofu—that have become staples of Chinese cuisine around the world. In 1950, the province of Xikang was dissolved and its territory was later split between the newly established Tibet Autonomous Region and the Province of Sichuan. The western and northwestern part of Sichuan is made up of Tibetan and Qiang autonomous areas.

Sichuan is the 6th-largest provincial economy of China, the largest in Western China and the second largest among inland provinces after Henan. As of 2021, its nominal GDP was 5,385 billion yuan (US$847.68 billion), ahead of the GDP of Turkey of 815 billion. Compared to a country, it would be the 18th-largest economy as well as the 19th most populous as of 2021.

There are many panda stations in the province and large reserves for these creatures, such as Chengdu Research Base of Giant Panda.

Names

It is commonly believed that the name ''Sichuan'' means "four rivers", and in folk etymology, this is usually taken to mean four of the province's major rivers: the Jialing, Jinsha (or Wu), Min, and Tuo. According to historical geographer Tan Qixiang, "four rivers" is an erroneous interpretation of the place's name. The name of the province is a contraction of the phrases ''Sì Chuānlù'' "Four Plain Circuits") and ''Chuānxiá Sìlù'' "Four Circuits of Chuanxia"),''Si'' (四) means "four", ''Chuan'' (川) means "plain", and ''Xia'' ("峡") could be understood as "gorge". ''Sì Chuānlù'' and ''Chuānxiá Sìlù'' are general names for the Four Circuits,. referring to the division of the existing imperial administrative circuit in the area into four during the Northern Song dynasty, which was Yizhou, Lizhou, Zizhou, and Kuizhou. The word ''chuan'' () here means "plain", not its normal meaning of "river" as popularly assumed. In addition to its postal map and Wade-Giles forms, the name has also been irregularly romanized as Szű-chuan and Szechuan.

In antiquity, the area of modern Sichuan including the now separated Chongqing Municipality was known to the Chinese as , in reference to the ancient states of Ba and Shu that once occupied the Sichuan Basin. Shu continued to be used to refer to the Sichuan region all through its history right up to the present day; several states formed in the area used the same name, for example, the Shu of the Three Kingdoms period, and Former Shu and Later Shu of the Ten Kingdoms period. Currently, both the characters for ''Shu'' and ''Chuan'' are commonly used as abbreviations for Sichuan.

History

Prehistory

The Sichuan Basin and adjacent areas of the Yangtze watershed were a cradle of indigenous civilizations dating back to at least the 15th century BC, coinciding with the Shang in northern China. The region had its own distinct religious beliefs and worldview. The earliest culture found in the region through archaeological investigation is the Baodun culture (2700–1750 BC) excavated in the Chengdu Plain.

Ba and Shu Kingdoms

The most important native states were those of Ba and Shu.

Ba stretched into Sichuan from the Han Valley in Shaanxi and Hubei down the Jialing River as far as its confluence with the Yangtze at Chongqing.

Shu occupied the valley of the Min, including Chengdu and other areas of western Sichuan. The existence of the early state of Shu was poorly recorded in the main historical records of China. It was, however, referred to in the ''Book of Documents'' as an ally of the Zhou. Accounts of Shu exist mainly as a mixture of mythological stories and historical legends recorded in local annals such as the '' Chronicles of Huayang'' compiled in the Jin dynasty (266–420), and the Han dynasty compilation ''Shuwang benji'' (). These contained folk stories such as that of Emperor Duyu () who taught the people agriculture and transformed himself into a cuckoo after his death. The existence of a highly developed civilization with an independent bronze industry in Sichuan eventually came to light with an archaeological discovery in 1986 at a small village named Sanxingdui in Guanghan, Sichuan. This site, believed to be an ancient city of Shu, was initially discovered by a local farmer in 1929 who found jade and stone artefacts. Excavations by archaeologists in the area yielded few significant finds until 1986 when two major sacrificial pits were found with spectacular bronze items as well as artefacts in jade, gold, earthenware, and stone. This and other discoveries in Sichuan contest the conventional historiography that the local culture and technology of Sichuan were undeveloped in comparison to the technologically and culturally "advanced" Yellow River valley of north-central China.

Qin dynasty

The rulers of the expansionist state of Qin, based in present-day Gansu and Shaanxi, were the first strategists to realize that the area's military importance matched its commercial and agricultural significance. The Sichuan basin is surrounded by the Hengduan Mountains to the west, the Qin Mountains to the north, and Yungui Plateau to the south. Since the Yangtze flows through the basin and then through the perilous Three Gorges to eastern and southern China, Sichuan was a staging area for amphibious military forces and a haven for political refugees.

Qin armies finished their conquest of the kingdoms of Shu and Ba by 316 BC. Any written records and civil achievements of earlier kingdoms were destroyed. Qin administrators introduced improved agricultural technology. Li Bing, engineered the Dujiangyan irrigation system to control the Min River, a major tributary of the Yangtze. This innovative hydraulic system was composed of movable weirs which could be adjusted for high or low water flow according to the season, to either provide irrigation or prevent floods. The increased agricultural output and taxes made the area a source of provisions and men for Qin's unification of China.

Han dynasty

Sichuan was subjected to the autonomous control of kings named by the imperial family of the Han dynasty. Following the declining central government of the Han dynasty in the second century, the Sichuan basin, surrounded by mountains and easily defensible, became a popular place for upstart generals to found kingdoms that challenged the authority of Yangtze Valley emperors over China.

Three Kingdoms

In 221, during the partition following the fall of the Eastern Han – the era of the Three Kingdoms – Liu Bei founded the southwest kingdom of Shu Han
