• Song Dynasty - The Song Dynasty was a ruling dynasty in China from 960 to 1279 AD. It was divided into two periods, the Northern Song (960?1127) and the Southern Song (1127?1279). The emperor was the ultimate authority, but he relied on officials who were selected based on their merit and skills rather than their family background or social status.
