Under Japanese rule, Miryang was the site of various clashes between the Korean independence movement and the occupation forces. During the March First Movement of 1919, approximately 13,500 Miryang residents took part in peaceful demonstrations in support of Korean independence. This led to the "Miryang massacre," in which 150 Korean civilians were shot by occupation troops. In November 1920, independence fighter Choe Su-bong built and detonated two bombs at the Miryang police station, destroying the structure. He attempted to kill himself but was unsuccessful; later he was put to death and his accomplices were imprisoned.
