Chen Tanxu

Emperor Xuan of Chen (陳宣帝) (530–582), personal name Chen Xu (陳頊), courtesy name Shaoshi (紹世), nickname Shili (師利), was an emperor of the Chen dynasty of China. He seized the throne from his nephew Emperor Fei in 569 and subsequently ruled the state for 13 years. He was considered to be a capable and diligent ruler, who at one point militarily expanded at the expense of Northern Qi. After Northern Qi fell to Northern Zhou in 577, however, Chen was cornered, and soon lost the gains it had previously made against Northern Qi. Emperor Xuan died in 582, leaving the state in the hands of his incompetent son Chen Shubao, and by 589, Chen would be destroyed by Northern Zhou's successor state Sui dynasty.
