Emperor Qinzong of Song
Emperor Qinzong (Emperor Chin-tsung; 23 May 1100 – 14 June 1161) was the ninth emperor of the Song Dynasty of China, and the last emperor of the Northern Song. His personal name was Zhao Huan. He reigned from January 1126 to January 1127.
The Jingkang Incident (simplified Chinese: 靖康事变; traditional Chinese: 靖康事變), the Humiliation of Jingkang (simplified Chinese: 靖康之耻; traditional Chinese: 靖康之恥), or The Disorders of the Jingkang Period (simplified Chinese: 靖康之乱; traditional Chinese: 靖康之亂)  took place in 1127 during the Jin-Song wars, when the invading Jurchen soldiers of the Jin Dynasty besieged and sacked Bianjing (Kaifeng), the capital of the Song Dynasty of China. The Jin forces abducted Emperor Qinzong, his father Emperor Emeritus Huizong, along with many members of the imperial court.
This ended the era known as the Northern Song Dynasty, when the Song Dynasty controlled most of China. The rest of the imperial family was forced to flee and establish a new government, now known as the Southern Song, at Lin'an, which was to become their capital. This incident is so named because this was the major incident during the short reign of Emperor Qinzong, whose era name was "Jingkang" (靖康).
