The Northern and Southern dynasties was a period of political division in the history of China that lasted from 420 to 589, following the tumultuous era of the Sixteen Kingdoms and the Eastern Jin dynasty. It is sometimes considered as the latter part of a longer period known as the Six Dynasties (220–589). Albeit an age of civil war and political chaos, it was also a time of flourishing arts and culture, advancement in technology, and the spread of Mahayana Buddhism and Daoism. The period saw large-scale migration of the Han people to the lands south of the Yangtze. The period came to an end with the unification of all of China proper by Emperor Wen of the Sui dynasty.

Yangtze or Yangzi is the longest river in Eurasia, the third-longest in the world. It rises at Jari Hill in the Tanggula Mountains of the Tibetan Plateau and flows 6,300 km (3,915 mi) in a generally easterly direction to the East China Sea. It is the fifth-largest primary river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country's population.
