The Jurchen were originally a Tungistic-speaking people inhabiting what are today portions of Manchuria and the Russian Far East. By the 11th century, the Jurchen had become vassals of the Liao (Khitan) Dynasty who considered them “uncivilized”. In 1115, Wayan Aguda united the various Jurchen tribes, declared himself emperor and named his dynasty “Jin” (meaning "gold"). By 1125, the Jurchen-led Jin Dynasty had unseated the Khitan-led Liao Dynasty. In 1127, the Jin captured the northern capital of the Song Dynasty, pushing the Song all the way south to the Yangtze River. During the reign of Wanyan Liang, the Jin Dynasty became increasingly Sinicized, adopting Han Chinese traditions and Confucian philosophy. The rise of the Mongols under Ghengis Khan in the early 13th century proved disastrous for the Jin Dynasty in spite of improvements to the Great Wall. They were forced to defend two fronts, against the Mongols in the north and against the Song in the South. It is said that the Mongols were amazed at the valor of the Jurchen warriors. A combined Song-Mongol allied army looted the Jin capital in 1233 and in the following year, the last Jin emperor Aizong committed suicide to avoid capture, bringing the Jurchen Jin Dynasty to an end.
