1940s
International attention to Shanghai grew in the 19th century due to European recognition of its economic and trade potential at the Yangtze River. During the First Opium War (1839–1842), British forces occupied the city. The war ended with the 1842 Treaty of Nanjing, which allowed the British to dictate opening the treaty ports, Shanghai included, for international trade. The Treaty of the Bogue signed in 1843, and the Sino-American Treaty of Wanghia signed in 1844 forced Chinese concession to European and American desires for visitation and trade on Chinese soil. Britain, France, and the United States all carved out concessions outside the walled city of Shanghai, which was still ruled by the Chinese.

In 1854, the Shanghai Municipal Council was created to manage the foreign settlements. Between 1860–1862, the Taiping rebels twice attacked Shanghai and destroyed the city's eastern and southern suburbs, but failed to take the city. In 1863, the British settlement to the south of Suzhou Creek (northern Huangpu District) and the American settlement to the north (southern Hongkou District) joined in order to form the Shanghai International Settlement. The French opted out of the Shanghai Municipal Council and maintained its own concession to the south and southwest.

Citizens of many countries and all continents came to Shanghai to live and work during the ensuing decades; those who stayed for long periods – some for generations – called themselves "Shanghailanders". In the 1920s and 1930s, almost 20,000 White Russians and Russian Jews fled the newly established Soviet Union and took up residence in Shanghai. These Shanghai Russians constituted the second-largest foreign community. By 1932,
