In 1645, under the support of Zheng Zhilong (郑芝龙) and others, Zhu Yujian (朱聿键) , the King of Tang (唐王) called himself Emperor in Fuzhou (福州) and Longwu in another year. Emperor Longwu launched a short Northern Expedition under the chairmanship of minister Huang Daozhou (黄道周). At the same time, he joined the peasant rebellion forces to resist the Qing Dynasty (清朝,1644-1911). However, with the surrender of Zheng Zhilong to the Qing Dynasty, the situation deteriorated. After being captured, Emperor Longwu died of hunger strike, and the Qing army quickly occupied most of the Southeast.
