Emperor Duānzōng (Chinese: 端宗, 1268 – May 8, 1278) was the penultimate emperor of Southern Song Dynasty of China who died in childhood and reigned from 1276-1278. He was also known as Lord Establishing-Nation (建國公). Born Zhào Shì (趙昰), he was the child of Emperor Duzong. He became Prince Ji (吉王) in 1274 and Prince Yi (益王) in 1276. Enthroned at Fuzhou on June 14, 1276, his reign had the era name of Jǐngyán (景炎). His temple name means "Final Ancestor".
Duanzong's younger brother was captured after Lin'an (present day Hangzhou) was invaded by the Mongols in 1276. Duanzong, along with another one of his younger brother Bing, escaped to Fujian and established the seat of the government in Fuzhou. In 1278, the Mongol forces were about to breakthrough Song's last line of defense and Duanzong was forced to flee. Accompanied by minister such as Lu Xiufu, Duanzong boarded a ship and fled to the province of Guangdong. He temporarily stayed in Hong Kong, with the Sung Wong Toi (literally Terrace of the Sung kings) in Kowloon City commemorating this event.
He was succeeded by his younger brother, Emperor Bing.
