Shanghai Municipal Police
The Shanghai Municipal Police (SMP; Chinese: 上海公共租界工部局警務處) was the police force of the Shanghai Municipal Council which governed the Shanghai International Settlement between 1854 and 1943, when the settlement was retroceded to Chinese control. Initially composed of Europeans, most of them Britons, the force included Chinese after 1864, and was expanded over the next 90 years to include a Sikh Branch (established 1884), a Japanese contingent (from 1916) and a volunteer part-time special police (from 1918).
