South Koreans protest on 14 December 2024
Here is the timeline of key events that led to this snap election:
3 December: Former President Yoon Suk Yeol declares emergency martial law in a late night televised address. Heavily-armed troops surround the National Assembly to block lawmakers from entering.
4 December: Just past 01:00 local time, 190 lawmakers, including 18 from Yoon’s own party, voted to overturn the law. Yoon rescinds his order about three hours later.
7 December: Opposition lawmakers try to impeach Yoon for the first time but fail after a boycott by members of his conservative People Power Party.
12 December: Yoon defends his martial law order, saying he did it to protect the country’s democracy. He vows to “fight to the end”.
14 December: Amid days and nights of protests – both by Yoon’s supporters and detractors – the National Assembly votes to impeach Yoon.
31 December: A district court issues a detention warrant for Yoon.
15 January: Some 3,000 police officers manage to detain Yoon at his heavily-fortified residence. This is their second attempt. In the first, hundreds of them faced a six-hour deadlock with his security detail.
19 January: The court grants a formal arrest warrant for Yoon, leading a mob of his supporters to riot, some even breaking into the courthouse.
26 January: Prosecutors indict Yoon on charges of leading an insurrection using his martial law bid.
4 April: The constitutional court upholds Yoon’s impeachment and formally removes him as president. Authorities announce the following week that a snap election will be held on 3 June.
