In the second year of Jingkang, during the reign of Emperor Qinzong of the Song Dynasty (1127 AD), the Jurchen (Jin) army marched southward, sweeping through undefended territories and swiftly capturing Bianliang (present-day Kaifeng, Henan), taking Emperors Huizong and Qinzong captive. This event is historically known as the "Humiliation of Jingkang." Following this catastrophe, Zhao Gou, younger brother of Emperor Qinzong (Zhao Huan), ascended the throne in Ying天府 (present-day Shangqiu, Henan) with the help of his ministers, establishing the Southern Song Dynasty. Later, the capital was moved to Lin'an (present-day Hangzhou, Zhejiang). The regime merely clung to survival, accepting all unreasonable demands from the Jurchen without resistance. By the time of Emperor Lizong, the appointment of the treacherous minister Jia Sidao as chancellor further plunged the court into chaos.
