Editing Jin dynasty (1115–1234) (section)

== Southward migration ==
After taking over northern China, the Jin became increasingly [[sinicised]]. Over the span of 20 years, the new Jurchen ruling class constituted around half of a larger pattern of migration southward into northern China. There, many Jurchens were granted land, which was then organised around a social structure based on hereditary military units: a {{lang|zh|mouke}} ('company') was a unit consisting of 300 households, and groups of 7–10 {{lang|zh|moukes}} were further organised into {{lang|zh|meng-an}} ('battalions').<ref>{{Citation |last=Mark C. Elliot |title=The Manchu Way: The eight banners and ethnic identity in late imperial China |page=60 |year=2001 |publisher=Stanford University Press}}</ref> The Jurchen ruling class ruled over an estimated 30&nbsp;million people. Many Jurchens intermarried with Han Chinese, though the ban on Jurchen nobility marrying outside of their ethnicity was only annulled in 1191.

Following the death of [[Emperor Taizong of Jin|Emperor Taizong]] in 1135, each of the next three emperors were the remaining grandsons of [[Emperor Taizu of Jin|Aguda]], each by a different one of his sons. [[Emperor Xizong of Jin|Emperor Xizong]] ({{r.}}1135–1149) studied the classics and wrote Chinese poetry. He adopted Han Chinese cultural traditions, but the Jurchen nobles had the top positions. Later in his life, Emperor Xizong became an alcoholic and executed many officials for criticising him. He also had Jurchen leaders who opposed him murdered, even those in the Wanyan clan. In 1149, he was murdered by a cabal of relatives and nobles, who made his cousin [[Wanyan Liang]] the next Jin emperor. Because of the brutality of both his domestic and foreign policy, Wanyan Liang was posthumously demoted from the position of emperor. Historians have consequently referred to him by his [[posthumous name]] "Prince of Hailing".<ref name="multiref1">{{Citation |last=Beck |first=Sanderson |title=Liao, Xi Xia, and Jin Dynasties 907–1234 |work=China 7 BC To 1279 |url=http://www.san.beck.org/AB3-China.html#9}}</ref>
