South Korea faces political upheaval as Yoon Suk Yeol's martial law attempt leads to his impeachment and a snap election.
SEOUL (Reuters) -South Koreans will go to the polls in a snap election on Tuesday, voting for a president to replace Yoon Suk Yeol, who was ousted from office in April after his brief martial law attempt sent shockwaves through the country.
Here are key events from martial law to Yoon's impeachment, arrest, and indictment, and election day.
-December 3, 2024: Shortly before 10:30 p.m. (1330 GMT), Yoon declares on national television he is imposing martial law to root out "anti-state forces" and overcome political deadlock.
An hour later the military issues a decree banning activity by political parties and lawmakers, and troops and police descend on the opposition-controlled parliament. Staffers use barricades and fire extinguishers to ward off special operations soldiers who arrive by helicopter and break windows as they enter parliament.
Lawmakers hop fences to avoid the security cordons and crowds of protesters gather.
-December 4: Defying the military's order, 190 lawmakers in the early hours unanimously vote to reject Yoon's declaration and troops begin to leave.
About three and a half hours later, Yoon gives another televised speech, announcing he is lifting martial law. The decree was in effect for about six hours.
Opposition parties submit motion to impeach Yoon.
U.S. Deputy Secretary of State Kurt Campbell says Yoon "badly misjudged" his decision to declare martial law, which was "deeply problematic" and "illegitimate."
-December 5: Yoon's People Power Party, although divided, decides to oppose his impeachment.
Yoon accepts the resignation of Defence Minister Kim Yong-hyun. Police investigate Yoon, Kim and the interior minister on accusations of treason and related crimes over the declaration of martial law after opposition parties and activists filed complaints.
-December 6: PPP leader Han Dong-hoon says Yoon must be removed from power for trying to impose martial law. Some party members urge Yoon to resign.
-December 7: Yoon addresses the nation to apologise, saying he will put his fate in the hands of the PPP but not saying he will resign.
A vote to impeach Yoon fails as the PPP boycotts, depriving parliament of a quorum.
-December 8: Prosecutors name Yoon as the subject of a criminal investigation over the martial law attempt. Ex-Defence Minister Kim is arrested.
-December 9: The justice ministry bars Yoon from leaving South Korea.
-December 10: Kwak Jong-geun, commander of the Army Special Warfare Command, tells a parliamentary committee that Yoon gave an order to "drag out" lawmakers from parliament after declaring martial law.
Ex-Defence Minister Kim attempts suicide in jail.
-December 11: Police try to search Yoon's office but are blocked from entering the building.
-December 12: Yoon says in another televised speech he will "fight to the end", alleging North Korea had hacked South Korea's election commission and expressing doubt over his party's landslide election defeat in April. The National Election Commission denies the claim.
-December 14: Parliament impeaches Yoon with the support of 204 of the 300 lawmakers in the one-chamber parliament. At least 12 PPP members vote to impeach.
Yoon's presidential powers are suspended, and Prime Minister Han Duck-soo becomes acting president.
-December 16: The Constitutional Court begins reviewing the impeachment case.
-December 27: Parliament impeaches and suspends acting President Han, less than two weeks after suspending Yoon. Finance Minister Choi Sang-mok assumes the position of acting president.
The court holds first public hearing in Yoon's impeachment case.
-December 31: The Seoul Western District Court approves an arrest warrant requested by the Corruption Investigation Office for High-ranking Officials (CIO) after Yoon failed to appear for questioning over insurrection allegations.
Yoon's lawyers say the arrest warrant is illegal and invalid because the CIO does not have the proper authority.
-January 3: Presidential guards and military troops prevent authorities from arresting Yoon in a tense six-hour stand-off inside his compound in the heart of Seoul.
-January 7: The Seoul Western District Court approves an extension of the arrest warrant after the CIO's failed attempt.
-January 14: The Constitutional Court adjourns the opening session of Yoon's impeachment trial within minutes, after the embattled leader did not attend court.
-January 15: Yoon agrees to leave his compound after around 3,000 police arrive for a second arrest attempt. Yoon says in a message he only submitted to avoid bloodshed, and the CIO says he refuses to answer questions. He is the first sitting South Korean president to be arrested.
-January 19: Hundreds of Yoon supporters storm a court building after his detention was extended, smashing windows and breaking inside. Yoon continues to refuse to answer questions.
-January 21: Yoon attends his impeachment trial at the Constitutional Court for the first time. When questioned by a justice, he denies ordering military commanders to drag lawmakers out of parliament.
-January 23: The CIO transfers its case to prosecutors and asks them to indict Yoon for insurrection and abuse of power.
-January 24-25: A court twice rejects requests by prosecutors for an extension of Yoon's detention while they do further investigation.
-January 26: Prosecutors indict Yoon on insurrection charges and ask that he be kept in custody.
-February 4-18: Constitutional Court holds five hearings in Yoon's impeachment trial.
-February 20: Seoul Central District Court questions Yoon concerning lawyers' request to cancel his arrest as "unlawful", holds preparatory hearing for insurrection trial.
Constitutional Court holds 10th hearing in Yoon's impeachment trial.
-February 25: Court holds final hearing in Yoon's impeachment trial. In his closing statement, Yoon defends his decisions as lawful and necessary to protect the country.
Yoon attended eight of the 11 hearings.
-March 9: Yoon walks free after prosecutors decide not to appeal a court decision to cancel his arrest warrant on insurrection charges. He spent 54 days in jail.
-April 4: The Constitutional Court rules to remove Yoon permanently from office.
-April 8: Government sets June 3 as date for snap election.
-April 27: The liberal Democratic Party names its former leader and 2022 presidential candidate Lee Jae-myung as its candidate.
-May 1: Acting president Han steps down to launch presidential run. Finance minister Choi resigns after Democratic Party vows to start impeachment proceedings, leaving education minister Lee Ju-ho as the country's third acting president since December.
The Supreme Court reverses an appeals court ruling that cleared Lee of criminal violations of election law, and ordered a new sentence, threatening his eligibility to run for office.
-May 3: Yoon's former labour minister, Kim Moon-soo, wins the main conservative People Power Party primary. Kim and Han spend the next week clashing over plans for a unity ticket.
-May 7: Appeals court delays ruling on Lee until after election.
-May 11: Han drops presidential bid after PPP confirms Kim as nominee.
