Myocheong’s Movement to Move the Capital to Seogyeong
Myocheong and Jeong Ji-sang of the Western Capital urged moving the capital there, proclaiming an emperor and attacking Jin; rebuffed, they rebelled in Seogyeong and were crushed within a year by government forces under Kim Bu-sik.
After Yi Ja-gyeom’s revolt Injong sought renewal. Myocheong and Jeong Ji-sang, natives of Seogyeong (Pyongyang), argued from geomancy that Gaegyeong’s energy was spent and Seogyeong auspicious, and urged moving the capital, styling the king emperor with his own era name, and attacking Jin. A palace, Daehwagung, was even built in Seogyeong, but the Gaegyeong aristocrats led by Kim Bu-sik opposed the plan on Confucian grounds of serving the great power.
In the first month of 1135 Myocheong rose at Seogyeong, naming his state Daewi, his era Cheongae and his army the Heaven-Sent Loyal Army. Kim Bu-sik’s forces took the city in the second month of 1136. Gaegyeong’s aristocracy grew stronger and Seogyeong’s standing fell. The historian Sin Chae-ho called it "the greatest event in a thousand years of Korean history", a clash between independent native thought and Confucian deference to China.
