A look at the context behind South Korea's shocking martial law edict

TOKYO — It may seem that the wild scenes in Seoul, with hundreds of armed troops and frantic lawmakers storming South Korea's parliament building after the president suddenly declared martial law, came out of nowhere.

But the chaotic events, which were still playing out as opposition leaders advanced an impeachment motion and called for President Yoon Suk Yeol's immediate resignation, should be seen in the context of South Korea's recent tumultuous political and social history.

These moments resonate with South Koreans in their daily lives, and as they look to explain Yoon's short-lived declaration of emergency martial law, even if there's still widespread confusion and anger over his decision.

From a doctors' strike, to an opposition leader narrowly avoiding prison amid a raft of court cases, to millions of people filling the streets in protest to drive out an elected leader, here is a look at some of those recent crucial developments:

A nationwide doctors' strike

For months, it has been health, not politics, that has been a major focus of many South Koreans.

An extended strike by thousands of junior doctors who have refused to see patients or attend surgeries has disrupted operations at hospitals across the country.

The strike, which is ongoing, began Feb. 20 in response to a government push to recruit more medical students.

Yoon's government has taken a hard line, warning that doctors must return to work or face license suspensions and prosecutions. He has said the strike poses ''a grave threat to our society.''

At issue is the government plan to raise South Korea's annual medical school admission cap by 2,000 from the current 3,058. The enrollment plan is meant to add up to 10,000 doctors by 2035 to cope with the country's fast-aging population. Officials say South Korea has 2.1 physicians per 1,000 people — far below the average of 3.7 in the developed world.

The striking doctors-in-training predict that doctors in greater competition would overtreat patients, increasing public medical expenses. Some critics say the striking junior doctors simply oppose the government plan because they believe adding more doctors would result in lower incomes.

A powerful opposition in turmoil

The current opposition leader, Lee Jae-myung, a firebrand liberal who narrowly lost the 2022 election to Yoon, has also been dogged by corruption claims.

Lee, who was stabbed in an attack and underwent surgery earlier this year, says Yoon's promotion of divisive politics has worsened an already toxic national discourse.

Last month Lee was convicted of violating election law and sentenced to a suspended prison term for making false statements during a presidential campaign. He faces three other trials over corruption and other criminal charges.

It remains unclear whether the Supreme Court will decide on any of the cases before the next presidential vote in March 2027.

Lee has steadfastly denied wrongdoing.

On Wednesday, he livestreamed himself climbing over a wall near parliament, one of a wave of lawmakers who dodged troops and police to get into the National Assembly.

Massive protests drive an elected president out of office

Perhaps the most epochal event in recent South Korean political history — and the one many people will be thinking of as Yoon faces the consequences of his declaration — was the downfall of conservative former President Park Geun-hye.

After near-daily protests in 2016 that saw millions take to the streets around the country, Park was the first democratically elected leader to be forced from office since democracy came to South Korea in the late 1980s.

Park, who was pardoned in late 2021 by her liberal rival and successor, former President Moon Jae-in, was serving a lengthy prison term for bribery and other crimes.

She was impeached by lawmakers in late 2016 and was formally removed from office and arrested the following year.

Among the main charges she faced was collusion with her longtime confidante, Choi Soon-sil, to take millions of dollars in bribes and extortion from some of the country's largest business groups, including Samsung, while she was in office.
