History of the Jin dynasty (266–420)

The Jin dynasty (Chinese: 晋朝; pinyin: Jìn Cháo, 266–420) was a major Chinese imperial dynasty. Following the devastation of the Three Kingdoms period, the Jin unified those territories and fostered a brief period of prosperity between 280 and 304 CE. However, during this period many social problems developed as well, the most pressing of which was the migration of non-Han tribes into Jin territory, to the point where they outnumbered the Han people in some regions.
