Emperor Daoguang(Mianning, 绵宁)Ⅲ

Daoguang's decision was a blow to China's effort to halt the influx of opium and deepened the Europeans' resolution to enter the vast Chinese market which eventually led to the First Opium War against Britain. Technologically and militarily inferior to the European powers and hobbled by the incompetence of the Qing government, China lost this war and was forced to surrender Hong Kong at the Treaty of Nanking in August 1842. Henceforth, Daoguang became the first emperor of the Qing Dynasty to have lost a portion of its sovereign territories. This was his personal tragedy also China’s tragedy.
