Emperor Xianwen of Northern Wei

Emperor Xianwen of Northern Wei ( 魏獻文帝), personal name Tuoba Hong, Xianbei name Didouyin (第豆胤), courtesy name Wanmin (萬民), was an emperor of the Xianbei-led Northern Wei dynasty of China. He was the first emperor in Chinese history who, after retiring at age 17 in favor of his 4-year-old son Emperor Xiaowen to become Taishang Huang in 471, continued to hold on to power until his death in 476 - when the official history states vaguely that he may have been killed by his stepmother Empress Dowager Feng.
