China was split North and South during the [[Song dynasty]] in the Middle Ages. The Mongols treated North and South China as separated countries. For example, Marco Polo writes of "Cathay" (North China) and "Manzi" (South China). By the time China was reunited by the [[Ming dynasty]] in 1368, North and South had drifted far apart. The dialect of [[Nanjing]] was chosen as a national standard. In the 1860s, Nanjing was depopulated by the [[Taiping Rebellion]]. As a result, its dialect was displaced by that of Beijing. Both cities speak dialects of the North Chinese type. | China was split North and South during the [[Song dynasty]] in the Middle Ages.
