Remnants of the Jìn court flee south of the Chang Jiang River and reestablish the Jìn court at Jiankang, southeast of Luoyang and Chang'an and near modern-day Nanjing, under the Prince of Longya.

When the news of the fall of Chang'an reaches the south, the prominent local families of Zhu, Gan, Lu, Gu, and Zhou support the proclamation of the Prince as Emperor Yuan of the Eastern Jìn Dynasty.

(Because the emperors of the Eastern Jìn Dynasty thus spring from the Langye line, the rival Wu Hu states, which do not recognize its legitimacy, will at times refer to Jìn as "Langye.")
