Shanghai is a municipality on China‘s central coast, at the point where the Yangtze River reaches the East China Sea. It is administered directly by China’s national government rather than by a province, one of only four such municipalities in the country, alongside Beijing, Tianjin, and Chongqing [1][6]. With a permanent population of 24.80 million at the end of 2024, spread across 6,340.5 square kilometers and 16 districts, it is China’s most populous city and its principal center of finance, trade, and shipping [1].

Origins and Early Growth

Settlement in the area predates the city’s name by centuries. The earliest administrative unit on record, Huating County, was established in 751 AD in what is now Shanghai’s Songjiang District [7]. Shanghai itself emerged later as a market town, founded in 991 AD, which had grown to roughly 12,000 residents by the early twelfth century [7]. Its population expanded sharply after 1127, when the fall of the Song dynasty capital at Kaifeng to Jurchen invaders sent large numbers of migrants south; by the end of the Southern Song in 1279, the area’s population had passed 250,000 [7]. In 1292, during the Yuan dynasty, the settlement was formally elevated to Shanghai County, and over the following centuries it grew into a center of cotton cultivation and textile production, long before any Western ship reached its harbor [7].

The Treaty Port Era

Shanghai’s modern transformation began with China’s defeat in the First Opium War. The 1842 Treaty of Nanjing opened a group of Chinese ports, including Shanghai, to foreign trade and residence and granted foreign nationals extraterritorial legal status [4]. Shanghai formally opened as a treaty port on November 17, 1843, and within weeks eleven foreign trading firms had set up operations in the city [3]. Growth was rapid: by 1853 Shanghai already handled more than half of China’s foreign trade, and across the full treaty-port era, from 1843 to 1941, it accounted for roughly half of the country’s gross foreign trade, with import shares averaging around 55 percent and export shares around 45 percent between 1870 and 1930 [3].

Foreign powers administered their own enclaves within the city. The British and American concessions merged to form the Shanghai International Settlement, which operated alongside a separate French Concession and the Chinese-administered old city [4]. The Settlement was run by the Shanghai Municipal Council and policed by the Shanghai Municipal Police, both of which held tax-raising powers and delivered municipal services independent of Chinese civil authority [4]. This period is remembered differently depending on perspective. Chinese historiography generally treats it as an era of foreign encroachment imposed through unequal treaties after military defeat. Historians of British imperial policy have instead described the arrangement as a form of informal imperialism, in which treaty privileges and self-governing foreign municipalities secured commercial dominance without the need for formal colonial annexation [4].

Civil War, Revolution, and Reform

The treaty-port system ended amid war and revolution. The Chinese Communist Party took control of Shanghai in May 1949, during the final stages of the Chinese Civil War [5]. Rather than seizing foreign assets immediately, Communist cadres initially pursued a cautious approach toward foreign-owned firms, prioritizing continued production and social stability over rapid nationalization; the transformation of foreign enterprises into state-run operations unfolded gradually through the early and mid-1950s [5].

Shanghai’s modern resurgence began four decades later. In April 1990, China’s State Council announced the creation of the Pudong New Area on the eastern bank of the Huangpu River, launching three national-level development zones at Lujiazui, Waigaoqiao, and Jinqiao [2]. An administrative commission followed in 1993, and Pudong received its own formal municipal government on August 6, 2000 [2]. Lujiazui became Shanghai’s financial core after the Shanghai branch of the People’s Bank of China relocated there in 1995 and the Shanghai Stock Exchange moved its headquarters there in 1997 [2]. In 2005 the State Council designated Pudong as China’s first pilot zone for comprehensive economic reform, and in 2009 the neighboring Nanhui district was merged into Pudong to extend its role as an international shipping and financial center [2]. Later milestones included completion of the 492-meter Shanghai World Financial Center in 2008, the launch of China’s first Free Trade Zone in 2013, the opening of Shanghai Disney Resort in 2016, and the maiden flight of the C919, China’s first domestically produced commercial airliner, in 2017 [2].

Economy and Daily Life

Shanghai today is China’s largest urban economy. According to the municipal government, the city’s GDP reached 5.67 trillion yuan, about 818 billion dollars, in 2025, a figure the city ranks fifth among the world’s cities by its own accounting; per capita disposable income stood at 92,000 yuan the same year [1]. The city recorded 4.51 trillion yuan in combined imports and exports in 2025 and hosts 1,076 regional headquarters of multinational corporations along with 636 foreign-invested research and development centers, with R&D spending equal to roughly 4.5 percent of GDP [1]. Shanghai Port has been the world’s busiest container port for 16 consecutive years, moving 55.06 million twenty-foot equivalent units in 2025 [1]. This dominance echoes a far older pattern: the share of China’s foreign exports that passed through Shanghai as re-exports, rather than goods made there, stood at 58 percent between 1870 and 1925 and remained nearly as high, 56 percent, between 1990 and 2009, underscoring the city’s long-standing role as a gateway linking China to global markets rather than purely a production base [3].

The city’s own vernacular, Shanghainese, is a dialect of Wu Chinese, a branch of the Chinese language family distinct from Mandarin [6]. Its sound system reflects the mixed origins of its speakers, most of whom descend from migrants who arrived from Jiangsu and Zhejiang provinces during the late nineteenth and early twentieth centuries, along with later influence from Mandarin and neighboring dialects [6]. Its everyday use has receded in recent decades as migration from other parts of China and the national promotion of Standard Mandarin have spread; most younger residents now speak Mandarin as a primary language, often with a Shanghainese accent [6]. The city otherwise maintains an active cultural calendar, hosting 1,565 exhibitions that drew 49 million visitors in 2025 and welcoming 9.36 million international visitor arrivals that year, in a city that maintains around 1,100 public parks [1].

Landmarks and Districts

Shanghai’s most recognizable image pairs two riverbanks. On the western side of the Huangpu River sits the Bund, the former waterfront core of the International Settlement’s banking and trading district [4]. Facing it across the water is Pudong’s Lujiazui financial district, developed as part of the Pudong New Area created in 1990; its skyline includes the Shanghai World Financial Center, completed in 2008 at a height of 492 meters, alongside towers added over the following decade [2]. The contrast between the two banks, low-rise, colonial-era buildings on one side and a dense modern skyline on the other, has become the single image most associated with the city, in China and abroad.

What Shanghai Is Best Known For

Outside China, Shanghai is known first as the country’s commercial and financial capital, a role it has played in two distinct eras: as the hub of foreign trade with China that emerged at scale after the 1840s, and again, on a far larger footing, as the engine of trade and finance rebuilt around Pudong since 1990 [3][2]. It is equally known for the visual contrast built into its skyline, where nineteenth- and early-twentieth-century riverfront architecture faces a cluster of twenty-first-century towers across the water, a contrast often used, in Chinese and international coverage alike, as shorthand for the pace of the country’s economic transformation.

Why Shanghai Matters

Shanghai’s importance rests on scale and position. As China’s largest city and operator of the world’s busiest container port, it functions as the country’s principal connection point to global trade, finance, and shipping networks [1]. Its economic output, reported at roughly 818 billion dollars for 2025 by the city’s own government, makes it a bellwether for the health of China’s export-driven economy, while Lujiazui remains the clearest physical symbol of the reforms that reshaped China’s economy after 1990 [1][2].
