Zhejiang is a coastal province in East China. Its capital and largest city is Hangzhou, with other notable cities including Ningbo, Yiwu and Wenzhou. Zhejiang is bordered by Jiangsu and Shanghai to the north, Anhui to the northwest, Jiangxi to the west and Fujian to the south. To the east is the East China Sea, beyond which lies the Ryukyu Islands. The population of Zhejiang stands at 64.6 million, the 8th largest in China. It is a major driving force in the Chinese economy and the birthplace of several notable people, including the Chinese Nationalist leader Chiang Kai-shek and entrepreneur Jack Ma. Zhejiang consists of 90 counties (incl. county-level cities and districts).

The area of Zhejiang was controlled by the Kingdom of Yue during the Spring and Autumn period. The Qin dynasty later annexed it in 222 BC. Under the late Ming dynasty and the Qing dynasty that followed it, Zhejiang's ports became important centers of international trade. It was occupied by the Wang Jingwei regime during World War II. After the establishment of the People's Republic of China, Zhejiang's economy became stagnant under Mao Zedong's policies. After the reform and opening up, Zhejiang grew to be considered one of China's wealthiest provinces, ranking fourth in GDP nationally and fifth by GDP per capita, with a nominal GDP of US$1.27 trillion as of 2024.

Zhejiang consists mostly of hills, which account for about 70% of its total area, with higher altitudes towards the south and the west. Zhejiang also has a longer coastline than any other mainland province of China. The Qiantang River runs through the province, from which it derives its name. Included in the province are three thousand islands, the most in China. The capital Hangzhou marks the end of the Grand Canal and lies on Hangzhou Bay on the north of Zhejiang, which separates Shanghai and Ningbo. The bay contains many small islands collectively called the Zhoushan Islands.

Hangzhou is a historically important city, and is considered a world city with a "Beta+" classification according to GaWC. It includes the notable West Lake. Various varieties of Chinese are spoken in Zhejiang, the most prominent being Wu Chinese. Zhejiang is also one of China's leading provinces in research and education. , three major cities in Zhejiang ranked in the world's top 130 cities (Hangzhou 10th, Ningbo 85th and Wenzhou 130th) by scientific research output, as tracked by Nature Index.

Ancient history

The area of modern Zhejiang was outside the major sphere of influence of Shang civilization during the second millennium BC. Instead, this area was populated by peoples collectively known as Dongyue.

The kingdom of Yue began to appear in the chronicles and records written during the Spring and Autumn period. According to the chronicles, the kingdom of Yue was in Northern Zhejiang. Shiji claims that its leaders were descended from the Xia founder Yu the Great. The "Song of the Yue Boatman" () was transliterated into Chinese and recorded by authors in North China or inland China of Hebei and Henan around 528 BC. The song shows that the Yue people spoke a language that was mutually unintelligible with the dialects spoken in north and inland China. The Sword of Goujian bears bird-worm seal script. Yuenü () was a swordswoman from the state of Yue. To check the growth of the kingdom of Wu, Chu pursued a policy of strengthening Yue.

Under King Goujian, Yue recovered from its early reverses and fully annexed the lands of its rival in . The Yue kings then moved their capital center from their original home around Mount Kuaiji in present-day Shaoxing to the former Wu capital at present-day Suzhou. With no southern power to turn against Yue, Chu opposed it directly and, in 333 BC, succeeded in destroying it. Yue's former lands were annexed by the Qin Empire in 222 BC and organized into a commandery named for Kuaiji in Zhejiang but initially headquartered in Wu in Jiangsu.

Han empire and the Three Kingdoms

Kuaiji Commandery was the initial power base for Xiang Liang and Xiang Yu's rebellion against the Qin Empire which initially succeeded in restoring the kingdom of Chu but eventually fell to the Han. Under the Later Han, control of the area returned to the settlement below Mount Kuaiji but authority over the Minyue hinterland was nominal at best and its Yue inhabitants largely retained their own political and social structures.

After the Han empire ended, Zhejiang was home to the warlords Yan Baihu and Wang Lang prior to their defeat by Sun Ce and Sun Quan, who eventually established the Kingdom of Wu. Despite the removal of their court from Kuaiji to Jianye (present-day Nanjing) and they continued development of the region and benefitted from influxes of refugees fleeing the turmoil in northern China. Industrial kilns were established and trade reached as far as Manchuria and Funan (southern Mainland Southeast Asia).

Zhejiang was part of the Wu during the Three Kingdoms. Wu (229–280), commonly known as Eastern Wu or Sun Wu, had been the economically most developed state among the Three Kingdoms (220–280). The historical novel Romance of the Three Kingdoms records that Zhejiang had the best-equipped naval force. The story depicts how the states of Wei () and Shu (), lack of material resources, avoided direct confrontation with the Wu. In armed military conflicts with Wu, the two states relied intensively on tactics of camouflage and deception to steal Wu's military resources including arrows and bows.

Six Dynasties

Despite the continuing prominence of Nanjing (then known as Jiankang), the settlement of Qiantang, the former name of Hangzhou, remained one of the three major metropolitan centers in the south to provide major tax revenue to the imperial centers in the north China. The other two centers in the south were Jiankang and Chengdu. In 589, Qiantang was raised in status and renamed Hangzhou.

Following the fall of Wu and the turmoil of the Wu Hu uprising against the Jin dynasty (266–420), most of elite Chinese families had collaborated with the non-Chinese rulers and military conquerors in the north. Some may have lost social privilege and took refuge in areas south of the Yangtze River. Some of the Chinese refugees from North China might have resided in areas near Hangzhou. For example, the clan of Zhuge Liang (181–234), a chancellor of the kingdom of Shu Han from Central Plain in north China, gathered together at the suburb of Hangzhou prefecture, forming an exclusive, closed village Zhuge Village (Zhege Cun), consisting of villagers all with family name "Zhuge." The village has intentionally isolated itself from the surrounding communities for centuries to this day and only recently came to be known in public. It suggests that a small number of powerful, elite Chinese refugees from the Central Plain might have taken refuge south of the Yangtze River. However, considering the mountainous geography and relative lack of agrarian lands in Zhejiang, most of these refugees might have resided in some areas in South China beyond Zhejiang, where fertile agrarian lands and metropolitan resources were available, mainly Southern Jiangsu, Eastern Fujian, Jiangxi, Hunan, Anhui and provinces where less cohesive, organized regional governments had been in place. Some refugees from North China might have found residence in South China depending on their social status and military power in the north. The rump Jin kingdom or the Southern dynasties vied against some Han elites from the Central Plain and south of the Yangtze River.

Sui and Tang empires

Zhejiang, as the heartland of the Jiangnan (Yangtze River Delta), remained the wealthiest area during the Six Dynasties (220 or 222–589), Sui and Tang. After being incorporated into the Sui dynasty, its economic richness was used for the Sui dynasty's ambitions to expand north and south, particularly into Korea and Vietnam. The plan led the Sui dynasty to restore and expand the network which became the Grand Canal of China. The Canal regularly transported grains and resources from Zhejiang, through its metropolitan center Hangzhou (and its hinterland along both the Zhe River and the shores of Hangzhou Bay) and from Suzhou and thence to the North China Plain. The débâcle of the Korean war led to Sui's overthrow by the Tang, who then presided over a centuries-long golden age for the country. Zhejiang was an important economic center of the empire's Jiangnan East Circuit and was considered particularly prosperous. Throughout the Tang dynasty, The Grand Canal had remained effective, transporting grains and material resources to North China plain and metropolitan centers of the empire. As the Tang dynasty disintegrated, Zhejiang constituted most of the territory of the regional kingdom of Wuyue.

Wuyue kingdom After the collapse of the Tang dynasty in 907, the entire area of what is now Zhejiang fell under the control of the kingdom Wuyue established by King Qian Liu, who selected Hangzhou (a city in the modern day area of Zhejiang) as his kingdom's capital. Despite being under Wuyue rule for a relatively short period of time, Zhejiang underwent a long period of financial and cultural prosperity which continued even after the kingdom fell.

After Wuyue was conquered during the reunification of China, many shrines were erected across the former territories of Wuyue, mainly in Zhejiang, where the kings of Wuyue were memorialized, and sometimes, worshipped as being able to dictate weather and agriculture. Many of these shrines, known as "Shrine of the Qian King" or "Temple to the Qian King", still remain today, with the most popularly visited example being that near West Lake in Hangzhou.

China's province of Zhejiang during the 940s was also the place of origin of the Hú family (Hồ in Vietnamese) from which the founder of the Hồ dynasty who ruled Vietnam, Emperor Hồ Quý Ly, came from.

Song empire

The Uyue kingdom was annexed by Song dynasty thus it re-established unity around 960. Under the Song empire, the prosperity of South China began to overtake that of North China. In 1127, Hangzhou became the capital of the Song dynasty under the name Lin'an, which was renowned for its prosperity and beauty, it was suspected to have been the largest city in the world at the time.

From then on, northern Zhejiang and neighboring southern Jiangsu have been synonymous with luxury and opulence in Chinese culture. The Mongol conquest and the establishment of the Yuan state in 1279 ended Hangzhou's political clout, but its economy continued to prosper. The famous Venetian traveler Marco Polo visited the city, which he called "Kinsay" (after the Chinese Jingshi, meaning "Capital City") claiming it was "the finest and noblest city in the world."
