See it on the Korean History map →What happened
The March 15, 1960 election was rigged to install Rhee's ally Lee Ki-poong as vice president. Protests broke out in Masan on election day; in April the body of a high-school protester, Kim Ju-yeol, killed by a police tear-gas shell, surfaced in Masan harbor. On April 19 (4·19 혁명) students marched on the presidential residence in Seoul and police opened fire; about 186 people died nationwide, by the usual count. After professors marched on April 25, Rhee resigned the next day.
Why it matters
It was the first time Koreans removed a ruler through mass protest, and it set the pattern for later democratic movements.
How we know
Newspapers, photographs and police records of the time, the National April 19th Cemetery in Seoul, and April 19 archives added to UNESCO's Memory of the World in 2023.
Still debated
How much US pressure and the army's refusal to fire on crowds, rather than protest alone, forced Rhee out is still discussed.

▸Syngman Rhee was toppled by April 19 RevolutionWell documented
The connection
Rhee, president since 1948, had changed the constitution twice to stay in office. In the March 15, 1960 election officials rigged the vote for his running mate, Lee Ki-poong. Protests grew after police killings; on April 26 Rhee resigned, and he went into exile in Hawaii, where he died in 1965.
When and how
Masan, Seoul and other cities, March 15 – April 26, 1960; students, then professors; US Ambassador Walter McConaughy urged Rhee to step down.
How we know
Rhee's resignation statement, newspapers and photographs of the time, and US State Department records.
Debates and open questions
How much Rhee, then 85, knew of the rigging and the killings, or whether aides around Lee Ki-poong kept him uninformed, is debated.
▸April 19 Revolution opened the struggle for Democratization of South KoreaWell documented
The connection
Rhee's fall brought a short-lived parliamentary Second Republic, and its example of students leading citizens into the streets returned in 1979, 1980 and 1987. Later movements claimed April 19 as their starting point, and the current constitution's preamble upholds the 'democratic ideals of April 19.'
When and how
1960, led by students; renamed from 'uprising' to 'revolution' in official usage in 1993; written into the 1987 constitution's preamble.
How we know
The constitution's text, the annual April 19 commemoration, and the National April 19th Cemetery in Seoul.
Debates and open questions
Whether the short-lived Second Republic failed through its own weakness or was simply cut down by the 1961 coup is debated.
▸April 19 Revolution was cut short by the coup of Park Chung-heeWell documented
The connection
The new parliamentary government of Prime Minister Chang Myon allowed free speech but struggled with street protests, party splits and a weak economy. On May 16, 1961, Major General Park and about 3,600 troops seized Seoul with little resistance, ending the democratic experiment after about a year.
When and how
Seoul, May 16, 1961; Park and Kim Jong-pil led officers of the military academy's 8th class.
How we know
Coup records, junta statements, and US cables showing Washington's surprise and later acceptance.
Debates and open questions
Whether Chang's government could have stabilized, and why President Yun Po-sun did not back the US commander's call to resist the coup.
