In 1127, the Manchu clans led by the Jin Dynasty emperors destroyed the Liao Dynasty, invaded Song, and captured the emperor, princes, and ministers. A prince at southern China was lucky to be the only one who was not taken by the Manchus, and after the invasion of northern China he succeeded the throne at Hangzhou. Because of this, historians named the Song that was before the invasion as Northern Song, and the one after the invasion as Southern Song. Southern Song made peace with the Manchus and existed until Kublai Khan of the Mongols conquered all of southern China in 1279.
