See it on the Korean History map →What happened
Yu Gwan-sun (유관순), a student at Ewha school in Seoul, joined the March 1919 demonstrations. When schools closed she returned home near Cheonan and, with relatives and local leaders, organized a protest at Aunae Market on April 1, 1919. Japanese military police fired on the crowd; both her parents were among those killed. Sentenced for leading the protest, she kept resisting in Seodaemun Prison, including a protest on the movement's first anniversary, and died there on September 28, 1920, after reported beatings.
Why it matters
She became South Korea's best-known symbol of the March 1st Movement, sometimes called Korea's Joan of Arc, and is taught to every schoolchild.
Legacy and how we know
Japanese court records of her trial, prison records, testimony of fellow prisoners and Ewha teachers, and her posthumous Order of Merit, raised to the highest grade in 2019.
Still debated
Her treatment and death in prison are known mainly from later testimony; her fame grew largely after 1945, which historians study as national memory-making.

The connection
After joining the Seoul demonstrations, Yu carried the movement home. She and local leaders spread word through nearby villages and gathered about 3,000 people at Aunae Market on April 1, 1919, to read a declaration and shout 'Manse!', one of hundreds of local protests that carried the movement beyond the cities.
When and how
Seoul in March 1919, then Aunae Market, Byeongcheon, near Cheonan in South Chungcheong Province, April 1, 1919.
How we know
Japanese court verdicts naming her as an organizer, police reports, and testimony from relatives and villagers.
Debates and open questions
How large her personal role was compared with older local organizers is hard to judge; postwar accounts may have enlarged it.

She led prisoners in shouting for independence on March 1, 1920, and was reportedly beaten and tortured. She died there that September, aged 17, one of many activists who died in custody.

Seodaemun Prison, Seoul, 1919–1920; she died September 28, 1920, and Ewha teachers recovered her body.
How we know
Prison and court records, Ewha school accounts, and fellow prisoners' later testimony; Seodaemun Prison is now a history museum.
Debates and open questions
The exact cause of death is not recorded in surviving documents; accounts of torture come from later testimony and are widely accepted in Korea.
