Five Dynasties and Ten Kingdoms period

The Five Dynasties and Ten Kingdoms Period (Chinese: 五代十國) was an era of political upheaval and division in Imperial China from 907 to 979 CE. Five dynastic states quickly succeeded one another in the Central Plain, and more than a dozen concurrent dynastic states, of which the most powerful and influential ten were known as the ten kingdoms, were established elsewhere, mainly in South China. It was a prolonged period of multiple political divisions in Chinese imperial history.
