Zhao Qi (趙禥), known by his temple name Duzong, was the fifteenth emperor of the Song Dynasty and the sixth of the Southern Song. He reigned for ten years, from 1264 to 1274, using the era name Xianchun (咸淳) from 1265.
According to the official history of the Song, his mother, Huang Dingxi, was a concubine of low rank who feared for her position when she became pregnant, and took drugs in an attempt to end the pregnancy.
The attempt failed, but the history records that the child was born weak in body and mind. His hands and feet were feeble and he moved awkwardly, he did not speak until he was seven, and he was never thought capable of ruling on his own.
