Early History Human activity in Zhenjiang dates to the early Neolithic period. Excavations at the Zuohu () site reveal a continuous cultural sequence from the
Majiabang to the Bronze Age Hushu culture. Adapted to the Ning-Zhen Hills, prehistoric inhabitants developed distinct ground-level dwellings that differ from contemporary Majiabang sites in the plains. The area is considered one of the early centers of rice cultivation in the lower Yangtze River valley. '' (), National Museum of China The Yi Hou Ze-
gui () unearthed at Dantu records the
Zhou investiture of an aristocrat at "
Yi," presumed to be the region where the vessel was discovered, including the granting of land and people, namely
fengjian. Despite ongoing scholarly debate, it remains the only bronze inscription interpreted as providing epigraphical support for
Sima Qian's account of Wu
Taibo's enfeoffment in the Jiangnan region. During the Spring and Autumn period, the region was incorporated into the
State of Wu and first appeared in historical records under the name
Zhufang (). In 543 BC, Qing Feng, a minister from the
State of Qi, fled to Wu seeking asylum following a failed power struggle. King Yuji of Wu granted him Zhufang as a fief. However, in 537 BC, King Ling of Chu led a coalition of feudal lords to besiege and capture Zhufang, subsequently executing Feng. Until the 3rd century CE, the apex of the Yangtze River's funnel-shaped estuary was located near present-day Zhenjiang and Yangzhou. During the early imperial era, the counties of
Dantu () and '''Qu'e''' () were established on the narrow coastal plains of this region. They served as major transit hubs for overland and river transport, linking the imperial center with the Lake Tai and Qiantang River regions. At the turn of the 3rd century CE, the Sun clan—who later founded the state of Eastern Wu—used Dantu as a primary administrative base, and the family patriarch Sun Jian was interred in nearby Qu'e. In 209, Sun Quan renamed this base "Jing" (), which subsequently became known as
Jingkou (). Situated about 80 km east of Nanjing (then Jianye or Jiankang), Jingkou developed into a strategic gateway on the lower Yangtze and an important military outpost guarding the capital. In 211, Sun Quan moved his seat of government to Jianye. To improve transport links between the new capital and the Kuaiji region while bypassing the navigational hazards of the Yangtze estuary, the Eastern Wu regime commissioned the Pogang Canal () and other waterways through the Ning–Zhen Hills. These canals connected the capital with its surrounding agricultural heartlands. Although located at a strategic transport hub, early Jingkou remained sparsely populated and underdeveloped. A hunting preserve southeast of the town served the Sun clan, while much of the surrounding land was organized as state farms (tuntian) under an agricultural command based in Biling ().
Six Dynasties to Tang Following the fall of the Central Plains and the southward retreat of the imperial court, hundreds of thousands of displaced northerners—many of them from north of the Huai River—were resettled in and around Jingkou and the neighboring Zhenjiang and Changzhou areas. Jingkou thus developed into a major garrison for controlling Jiangnan, defending the capital Nanjing, and resisting seaborne incursions. In the early 4th century, Xi Jian—a general of northern émigré origin and regional governor of Xu—strategically garrisoned Jingkou to counter internal rebellions. He relocated his military headquarters and the nominal Xu provincial administration from the north bank of the Yangtze to Jingkou, establishing the new "Northern Headquarters" (
Beifu, ) there. Building on this foundation, Xie Xuan, who oversaw the defense of the lower Yangtze, formally organized the
Beifu Army by recruiting soldiers from the northern migrant communities. This force of 80,000 troops became a central political and military power after defeating a numerically superior invading force in the
Battle of Fei River in 383 CE. In the wake of a series of political struggles, the
Beifu Army grew increasingly autonomous, with its command transitioning from the hands of top-tier aristocratic families to those of lower-ranking gentry. At the turn of the 5th century,
Liu Yu, a commander who hailed from Jingkou's own migrant community, rose to prominence as the leader of the
Beifu Army. He eventually overthrew the Eastern Jin and founded his own dynasty, the Liu Song. In his last will, Liu Yu decreed that Jingkou must be governed by a trusted imperial clansman. Following the Liu Song's successful campaigns to recover territory in the north, the original Xu province or Xuzhou, with its seat in
Pengcheng, was reclaimed. To distinguish it from the original one, the administration based in Jingkou was officially renamed the Southern Xu Province (Nan Xuzhou, ). Owing to their special status under the immigrant registration system, displaced northern population in Jingkou initially enjoyed exemptions from taxes and corvée labor. In 454, the Liu Song court began taxing these communities, and the institutional role of the Northern Headquarters steadily declined, finally was abolished in 484, and in 502 the Liang government ended the remaining privileges for immigrant groups. In 589, Sui forces crossed the Yangtze to seize Jingkou and then advanced on Jiankang, capital of the Southern dynasties. An edict ordered virtually the entire city of Jiankang to be demolished. Jiankang's status was accordingly downgraded, and for much of the period until 887, Jiankang served only as a subordinate county under Jingkou, later known as Runzhou. This shift made Runzhou the main regional administrative centre of the lower Yangtze. The city's position was further strengthened by the Jiangnan, or Zhexi, Canal—named for the region north and west of the Qiantang River (modern southern Jiangsu and northern Zhejiang). Begun in 605 under
Emperor Yang of Sui, largely along earlier waterways, this southern leg of the Grand Canal linked Jingkou with Yuhang (modern Hangzhou) and more directly connected the Yangtze Delta with northern China. From the Tang onward, Runzhou developed into a center for handicrafts and state-supervised production. Local
silk gauze (
luo, ) remained a regular tribute item through the Song, supported by state-operated workshops. Significant regional silver production is suggested by the Dingmao Bridge () hoard—containing over 900 silver objects—as well as late Tang records of silver ingot tributes, which are generally associated with state-managed metalworking in the region.
Song to Qing dynasties The city flourished from the 10th to 13th centuries, when it produced fine silks, satins, and silverware for the
Song emperors. The 11th-century scientist and statesman
Shen Kuo composed his 1088
Dream Pool Essays during his retirement in a garden estate on the outskirts of the city. It was taken by the
Mongolians during their 1275 campaign against the
Southern Song capital at
Hangzhou. Under their
Yuan dynasty, some
Nestorian Christians were reported living in the city. The city fell to
Xu Da on 17 March 1356. According to
Odoric of Pordenone, Zhenjiang had a vast amount of shipping, more so than any other city in the world. The ships which worked the city were painted white and often doubled as businesses such as taverns or other gathering spots. Under the
Ming, it was the seat of a prefecture (
fu) of
Nanzhili, the Southern Directly-Administered District around the secondary capital
Nanjing. The
Southern Ming placed the town under
Zheng Zhifeng, brother of
Zheng Zhilong and favorite uncle of
Koxinga. He was fooled into wasting most of his ammunition against a feint, however, and forced to abandon the city to the
Manchus on 1 June 1645. and
Lake Tai east of
Nanjing ("Kiangning"), from
Martino Martini's 1655
Novus Atlas Sinensis. The river marked west of the city is the
Grand Canal. Under the
Qing, Zhenjiang was a city of half a million surrounded by a series of brick
city walls up to high. It continued as a prefectural seat, first under the "Right" Governor of
Jiangnan at
Suzhou and later under the governor of
Jiangsu in Jiangning (now Nanjing). After a fierce resistance, Zhenjiangromanized at the time as Chinkiangwas
captured by the
British on 21 July 1842 during the
First Opium War. As this left the path open to
Nanjing, its fall prompted the
unequal Treaty of Nanking to avoid further conflict. A decade later, massive floods of the
Yellow River altered its course from south to north of
Shandong and closed the northern path of the Grand Canal. Soon after, Zhenjiang was sacked by the
Taiping rebels in 1853. It was recaptured by the Qing in 1858 and opened as a
treaty port in 1861. Into the 1870s,
Chaozhou merchants used their connections in Zhenjiang to make it a regional distribution center for
opium purchased from the foreign merchants in
Shanghai; when
David Sassoon attempted to avoid taxation by delivering his cargoes directly to the opium merchants in Zhenjiang, the Chinese organized to intimidate his customers and then bought out his failed organization. The population was estimated at 168,000 in 1904.
Modern China The southern part of the Grand Canal was obstructed in the early 20th century, although by that point the city was connected by
rail to
Shanghai and
Nanjing. The
Kuomintang government revoked the British concession at Zhenjiang in 1929. From 1928 to 1949, while
Nanjing served as the capital of the
Republic of China, Zhenjiang served as the provincial capital for Jiangsu. During
World War II, the city fell to
Japan's
Shanghai Expeditionary Army in the morning of 8 December 1937, shortly before
the capture of Nanjing, but local resistance to the Japanese is still celebrated among the Chinese. When the
Communists won the
Chinese Civil War and relocated the capital to
Beijing, Nanjing resumed its role as Jiangsu's capital. Zhenjiang is still one of China's busiest ports for domestic commerce, serving as a hub for trade among
Jiangsu,
Anhui, and
Shanghai. The trade mostly consists of grain, cotton, oils, and lumber. The other main industries are mostly in the field of food processing and paper pulp manufacturing. ==Geography==
