Months of peaceful mass rallies in 2016–17 that ended with President Park Geun-hye's impeachment and removal.
See it on the Korean History map →What happened
In October 2016 the broadcaster JTBC revealed that Choi Soon-sil, a longtime confidante of President Park Geun-hye with no official post, had edited Park's speeches; other reports showed she used her access to extract tens of millions of dollars from conglomerates, Samsung included. Weekly candlelight rallies (촛불집회) filled Seoul's Gwanghwamun for five months without serious violence. The National Assembly impeached Park 234–56 on December 9; on March 10, 2017, the Constitutional Court removed her unanimously. Moon Jae-in won the snap election.
Why it matters
Park became the first South Korean president removed from office, peacefully and through parliament and courts; the rallies became a model of nonviolent civic pressure.
How we know
The court ruling, Assembly vote records, the convictions of Park, Choi and Samsung's Lee Jae-yong, and crowd counts; organizers claimed about 16 million cumulative attendees, police far fewer.
Still debated
Park's supporters call it a political purge; crowd sizes are disputed, as is how much the streets, versus the evidence, swayed the outcome.

▸Sewol ferry disaster fueled anger behind Candlelight protests and Park Geun-hye's impeachmentMostly agreed
The connection
Families' campaign for a full Sewol inquiry met government resistance for two years, and questions about Park's missing 'seven hours' festered. When the Choi Soon-sil scandal broke, rally crowds carried yellow ribbons and Sewol banners, and the impeachment motion cited Park's failure to protect lives that day.
When and how
Seoul's Gwanghwamun Square, where Sewol families had kept a protest tent since 2014, became the rallies' center in 2016–17.
How sure are we?
The impeachment bill's text, rally banners and surveys; the Constitutional Court did not count the Sewol charge as grounds for removal.
Debates and open questions
How much Sewol anger, rather than the corruption evidence itself, moved the public; pollsters and historians weigh it differently.
▸Candlelight protests and Park Geun-hye's impeachment showed the strength of Democratization of South KoreaWell documented
The connection
Millions protested for months without serious violence, and the outcome came through institutions: an Assembly vote, a unanimous court ruling, and a snap election within 60 days, as the constitution requires. Thirty years after 1987, it showed citizens and courts could remove a sitting president lawfully.
When and how
Seoul and other cities, October 2016 to March 2017; ruling March 10, 2017; election May 9, 2017.
How we know
The Constitutional Court decision, Assembly records, and the absence of military intervention, unlike the crises of 1961 and 1980.
Debates and open questions
Critics, mainly on the right, call it mob pressure dressed as law; defenders call it democracy working. That split still shapes South Korean politics.
▸Candlelight protests and Park Geun-hye's impeachment set the impeachment precedent for Yoon Suk-yeol's martial law and removalWell documented
The connection
Park's 2017 case set the playbook: an Assembly impeachment vote, suspension of powers, then Constitutional Court review. Roh Moo-hyun's 2004 impeachment had been rejected, so Park's was the first removal. When Yoon was impeached in December 2024, protesters again filled the streets, now waving K-pop light sticks, and the court removed him unanimously.
When and how
Seoul: Park removed March 10, 2017; Yoon impeached December 14, 2024, and removed April 4, 2025, both by unanimous 8–0 rulings.
How we know
The two Constitutional Court decisions, which apply the same legal test: a grave violation of the constitution or law.
Debates and open questions
Whether frequent impeachments, including of many Yoon-era officials, strengthen accountability or turn the tool into routine partisan warfare.
