Emperor Qinzong of Song (23 May 1100 – 14 June 1161), personal name Zhao Huan, was the ninth emperor of the
Song dynasty in China and the last emperor of
The Northern Song Dynasty.
Emperor Qinzong was the eldest son and
heir apparent of
Emperor Huizong. His mother was Emperor Huizong's empress consort,
Empress Wang. In 1126, when the forces of the
Jin Empire invaded the Song Empire during the
Jin–Song Wars, Emperor Huizong abdicated and passed on his throne to Emperor Qinzong, and then assumed the title
Taishang Huang ("Retired Emperor") himself. Left to deal with the Jin invasion, Emperor Qinzong appointed the general Li Gang (李綱) to lead the Song military to fend off the invaders. However, the emperor was not a decisive leader and often made poor judgments. Eventually, he removed Li Gang from his appointment in the hope of starting peace talks with the Jin Empire. However, Jin forces eventually breached the walls of the Song capital,
Bianjing, in 1127 and occupied the city in an event historically known as the
Jingkang Incident ("Jingkang" was the
era name of Emperor Qinzong's reign). Emperor Qinzong, along with his father Emperor Huizong and the rest of their family, were taken prisoner by Jin forces. This event also marked the end of the Northern Song dynasty. One of Emperor Huizong's sons managed to escape to southern China, where he reestablished the empire as the Southern Song dynasty and became historically known as
Emperor Qinzong and his father were demoted to the status of commoners on 20 March 1127 and deported to
Huining Prefecture, the Jin capital, on 13 May 1127. In 1128, the two former Song emperors were forced to wear mourning dress and pay homage to the ancestors of the Jin emperors at their ancestral temple in Huining Prefecture.
 Furthermore, the Jurchen ruler,
Emperor Taizong, gave the two former Song emperors contemptuous titles to humiliate them: Emperor Qinzong was called "Marquis Chonghun" (重昏侯; literally "Doubly Besotted Marquis") while Emperor Huizong was called "Duke Hunde" (昏德公; literally "Besotted Duke").
In 1141, as the Jin Empire normalised relations with the (Southern) Song Empire, the Jurchens renamed Emperor Qinzong's title to the more neutral-sounding "Duke of Tianshui Commandery" (天水郡公), which is based on a
commandery located in the upper reaches of the
Wei River. A few months later, the former emperor started receiving a stipend due to his nobility status. He lived the rest of his life as a captive in the Jin Empire, which used him as a hostage to put pressure on the Song Empire.
Emperor Qinzong died as a sick and broken man in 1161.
 He was 61. His
temple name means "Esteemed Ancestor".
