Later Three Kingdoms Period

The Later Three Kingdoms period (889-935 CE) of ancient Korea saw a partial revival of the old three kingdoms which had dominated the peninsula from the 1st century BCE to the 7th century CE. After the Unified Silla kingdom had ruled Korea alone from 668 CE, it slowly began to decline and the power vacuum this created led to several rebellious states rising up and taking on the old historical names of Korea's ancient kingdoms. A messy period of alliances and in-fighting followed, but one state would once again establish a dominant position – Goryeo, itself named in homage to the earlier northern Goguryeo kingdom – and form a unified Korean state and a dynasty which would last for over 500 years.
