Beginning in the late 19th and early 20th centuries, the baekjeong began to resist the open social discrimination that existed against them. In 1900, leaders from 16 counties petitioned the mayor of Jinju to wear the same clothes and hats as other people. When others in the north refused to wear the humiliating garb traditionally expected of them and were jailed, an effort was made to release them. Growing industrialism in Korea began to erode baekjeong dominance over certain occupations, particularly as the Japanese began to control slaughterhouses and exploit them as employees.
