Koryo

At the later days of United Shilla, the country was again divided into the post-three kingdoms. Here Koryo's founding father Wang Gun reunified them into one.

Koryo's ruling ideology was "to recover the glory of Koguryo" by reconquering the lost territory in China. Thus, it was named "Koryo", from which the name of today's "Korea" came from. Though it failed to recapture the lost Manchuria, it made efforts to do so.

Based on Buddhism, Koryo developed the Buddhist culture. And an aristocratic society was developed. Koryo created the "metal print-setting" which was the first one in world history and 200 years before the one from Europe was invented. In addition, Koryo's "blue pottery" was so creatively sophisticated and elaborated that even the contemporaries could not make it same as the original one.
