Shanghai contains the administrative territorial entity Hongkou
Rise and golden age
In the 19th century, international attention to Shanghai grew due to European recognition of its economic and trade potential at the Yangtze. During the First Opium War (1839–1842), British forces occupied the city. The war ended in 1842 with the Treaty of Nanking, which opened Shanghai as one of the five treaty ports for international trade. The Treaty of the Bogue, the Treaty of Wanghia, and the Treaty of Whampoa (signed in 1843, 1844, and 1844, respectively) forced Chinese concession to European and American desires for visitation and trade on Chinese soil. Britain, France, and the United States all established a presence outside the walled city of Shanghai, which remained under the direct administration of the Chinese.The Chinese-held Old City of Shanghai fell to rebels from the Small Swords Society in 1853, but was recovered by the Qing government in February 1855. In 1854, the Shanghai Municipal Council was created to manage the foreign settlements. Between 1860 and 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.Seven of the districts govern Puxi (lit. "The West Bank", or "West of the River Pu"), the older part of urban Shanghai on the west bank of the Huangpu River. These seven districts are collectively referred to as Shanghai Proper (上海市区) or the core city (市中心), which comprise Huangpu, Xuhui, Changning, Jing'an, Putuo, Hongkou, and Yangpu.
Pudong (lit. "The East Bank", or "East of the River Pu"), the newer part of urban and suburban Shanghai on the east bank of the Huangpu River, is governed by Pudong New Area (浦东新区).Seven of the districts govern suburbs, satellite towns, and rural areas farther away from the urban core: Baoshan, Minhang, Jiading, Jinshan, Songjiang, Qingpu, and Fengxian.Chongming District comprises the islands of Changxing and Hengsha and most—but not all—of Chongming Island.
The former district of Nanhui was absorbed into Pudong District in 2009. In 2011, Luwan District merged with Huangpu District. As of 2015, these county-level divisions are further divided into the following 210 township-level divisions: 109 towns, 2 townships, and 99 subdistricts. Those are in turn divided into the following village-level divisions: 3,661 neighborhood committees and 1,704 village committees.There is a sizable Korean community of Shanghai and Japanese community of Shanghai largely in the Minhang District.
