Chŏng Mong-ju

Chŏng Mong-ju (Korean: 정몽주; Hanja: 鄭夢周, January 13, 1337 – May 4, 1392), also known by his art name P'oŭn (포은), was a Korean statesman, diplomat, philosopher, poet, calligrapher and reformist of the Goryeo period. He was a major figure of opposition to the transition from the Goryeo (918–1392) to Joseon (1392–1897) periods.

Being the last great personality from the late Goryeo period, exceptional in all aspects of academics, diplomacy, economics, military and politics, and trying to reform Goryeo while maintaining the declining kingdom, he opposed to the Goryeo general Yi Sŏng-gye (the first king of the future Joseon Dynasty) who was a radical revolutionary against the rotten Goryeo Dynasty. Due to his loyalty to Goryeo, Chŏng Mong-ju was eventually assassinated by five men of Yi Pang-wŏn (the fifth son of Yi Sŏng-gye and the third king of Joseon Dynasty).
