Biography
Living at the violent sunset of the Goryeo dynasty, Chŏng Mong-ju was a polymath—a poet, diplomat, and Neo-Confucian philosopher—who served his kingdom with unshakable integrity. As a trusted minister, he undertook crucial diplomatic missions to the Ming court in China to secure recognition and peace. His true legacy, however, was forged in resistance. He became the intellectual and moral leader of the faction opposing the military commander Yi Seong-gye, who sought to overthrow Goryeo and found a new Joseon dynasty. Chŏng's steadfast loyalty to the old order made him a target. His assassination on the Sonjuk Bridge, orchestrated by Yi's son, transformed him from a statesman into a potent national icon of loyalty, celebrated for centuries in Korean culture and folklore.
