Goryeo
Goryeo was founded in 918 by Wang Geon, a general from Kaesong, who reunited Korea after the breakup of Unified Silla by 936; the modern name Korea comes from Goryeo. Its kings built a centralised state on the Chinese model with civil service examinations, while powerful aristocratic families dominated the court.
Buddhism was the state religion, and Goryeo is famous for its jade-green celadon pottery and for the Tripitaka Koreana, the Buddhist scriptures carved on more than 80,000 woodblocks. The kingdom repelled Khitan invasions, but from 1170 military officers seized power. After decades of resistance it made peace with the Mongols in 1259 and became a vassal of the Yuan, with its kings marrying Yuan princesses. Weakened by pirate raids and factional strife, it was overthrown by General Yi Seong-gye in 1392.
