Yining

Yining (義寧) was the era name of China's Sui (隋) under Emperor Gong (恭帝), and the last era name of the Sui dynasty. It was used for seven months, from November 617 to May 618. In November 617, Li Yuan (李淵) enthroned Emperor Gong in Chang'an and changed the era name. However, Emperor Yang of Sui (煬帝) remained on the throne at Jiangdu (江都), so until March 618 the Sui officially used two era names, Daye (大業) and Yining. In May 618, Emperor Gong abdicated in favor of Li Yuan and stepped down from the throne, whereby the Tang (唐) was founded and the Sui perished.

Other era names used during the same period include Daye (大業, 605–618) used by Emperor Yang of Sui; Changda (昌達), a minor era name used by the Chu (楚) regime of Zhu Chan (朱粲); Taiping (太平), a minor era name used by the Chu regime of Lin Shihong (林士弘); Dingchou (丁丑), a minor era name used by the Xia (夏) regime of Dou Jiande (竇建德); Yongping (永平), a minor era name used by the Wei (魏) regime of Li Mi (李密); Tianxing (天興), used by Liu Wuzhou (劉武周); Yonglong (永隆), a minor era name used by the Liang (梁) regime of Liang Shidu (梁師都); Zhengping (正平), used by Guo Zihe (郭子和); Qinxing (秦興), a minor era name used by the Qin (秦) regime of Xue Ju (薛擧); Mingfeng (鳴鳳, or 鳳鳴), a minor era name used by the Liang (梁) regime of Xiao Xian (蕭銑); and Tongsheng (通聖), used by Cao Wuche (曺武徹).

Adoption

On the 16th day of the 11th month of the 13th year of Daye (大業) (19 December 617), the era name was changed to Yining (義寧).
