These women helped bring down a president - now they say they feel invisible

An Byunghui was in the middle of a video game on the night of 3 December when she learned that the South Korean president had declared martial law.

She couldn't quite believe it - until the internet blew up with the evidence. The shock announcement from then-president Yoon Suk Yeol, the now-famous shots of soldiers breaking down the windows of the National Assembly and MPs scaling the walls to force their way into the building so they could vote the motion down.

Within hours, thousands had spurred into protest, especially young women. And Byunghui joined them, travelling hundreds of miles from Daegu in the south-east to the capital Seoul.

They turned up not just because Yoon's decision had alarmed and angered them, but to protest against a president who insisted South Korea was free of sexism - despite the deep discrimination and flashes of violence that said otherwise.

They returned week after week as the investigation into Yoon's abuse of power went on - and they rejoiced when he was impeached after four dramatic months.

And yet, with the country set to elect a new president on 3 June, those very women say they feel invisible again.

The two main candidates have been largely silent about equality for women. A polarising subject, it had helped Yoon into power in 2022 as he vowed to defend men who felt sidelined in a world that they saw as too feminist. And a third candidate, who is popular among young men for his anti-feminist stance, has been making headlines.

For many young South Korean women, this new name on the ballot symbolises a new fight.

"So many of us felt like we were trying to make the world a better place by attending the [anti-Yoon] rallies," the 24-year-old college student says.

"But now, I wonder if anything has really improved… I can't shake the feeling that they're trying to erase women's voices."

When Byunghui arrived at the protests, she was struck by the atmosphere.

The bitter December cold didn't stop tens of thousands of women from gathering. Huddling inside hooded jackets or under umbrellas, waving lightsticks and banners, singing hopeful K-pop numbers, they demanded Yoon's ouster.

"Most of those around me were young women, we were singing 'Into the World' by Girls' Generation," Byunghui says.

Into the World, a hit from 2007 by one of K-pop's biggest acts, became an anthem of sorts in the anti-Yoon rallies. Women had marched to the same song nearly a decade ago in anti-corruption protests that ended another president's career.

"The lyrics - about not giving up on this world and dreaming of a new world," Byunghui says, "just overwhelmed me. I felt so close to everyone".

There are no official estimates of how many of the protesters were young women. Approximately one in three were in their 20s or 30s, according to research by local news outlet Chosun Daily.

An analysis by BBC Korean found that women in their 20s were the largest demographic at one rally in December, where there were 200,000 of them - almost 18% of those in attendance. In comparison, there were just over 3% of men in their 20s at that rally.

The protests galvanised women in a country where discrimination, sexual harassment and even violence against them has long been pervasive, and the gender pay gap - at 31% - is the widest among rich nations.

Like in so many other places, plummeting birth rates in South Korea too have upped the pressure on young women to marry and have children, with politicians often encouraging them to play their part in a patriarchal society.

"I felt like all the frustration that has built up inside me just burst forth," says 23-year-old Kim Saeyeon . "I believe that's why so many young women turned up. They wanted to express all that dissatisfaction."

For 26-year-old Lee Jinha, it was the desire to see Yoon go: "I tried to go every week. It wasn't easy. It was incredibly cold, super crowded, my legs hurt and I had a lot of work to do… but it was truly out of a sense of responsibility."

That is not surprising, according to Go Min-hee, associate professor of political science at Ewha Women's University, who says Yoon had the reputation of being "anti-feminist" and had "made it clear he was not going to support policies for young women".

There were protests on the other side too, backing Yoon and his martial law order. Throughout, many young South Korean men have supported Yoon, who positioned himself as a champion of theirs, mirroring their grievances in his presidential campaign in 2022.

These men consider themselves victims of "reverse discrimination", saying they feel marginalised by policies that favour young women. One that is often cited is the mandatory 18 months they must spend in the military, which they believe puts them at a severe disadvantage compared to women.

They label as "man haters" those women who call themselves feminists. And they have been at the heart of a fierce online backlash against calls for greater gender equality.

These groups have long existed, mostly out of the public eye. But over the years they moved closer to the mainstream as their traction online grew, especially under Yoon.

It was them that Yoon appealed to in his campaign pledges, vowing to abolish the Ministry of Gender Equality and Family, saying it focused too much on women's rights.

And he consistently denied systemic gender inequality existed in South Korea, which ranks near the bottom on the issue among developed countries.

But his message hit home. A survey by a local newspaper the year before he was elected had found that 79% of young men in their 20s felt "seriously discriminated against" because of their gender.

"In the last presidential election, gender conflict was mobilised by Yoon's party," says Kim Eun-ju, director of the Center for Korean Women and Politics. "They actively strengthened the anti-feminist tendencies of some young men in their 20s."

During Yoon's term, she says, government departments or publicly-funded organisations with the word "women" in their title largely disappeared or dropped the reference altogether.

The impact has been polarising. It alienated young women who saw this as a rollback of hard-won rights, even as it fuelled the backlash against feminism.

Byunghui saw this up-close back home in Daegu. She says anti-Yoon protests were overwhelmingly female. The few men who came were usually older.

Young men, she adds, even secondary school students, would often drive past the protests she attended cursing and swearing at them. She says some men even threatened to drive into the crowd.

"I wondered if they would have acted this way had the protest been led by young men?"

With Yoon gone, his People Power Party (PPP) is in disarray and still reeling from his fall.

And this is the first time in 18 years that there is no woman among the seven candidates runnning for president. "It's shocking," Jinha says, "that there's no-one". In the last election, there were two women among 14 presidential candidates.

The PPP's Kim Moon-soo is trailing frontrunner Lee Jae-myung, from the main opposition Democratic Party (DP). But young women tell the BBC they have been disappointed by 61-year-old Lee.

"It's only after criticism that that there were no policies targeting women that the DP began adding a few," Saeyeon says. "I wish they could have drawn a blueprint for improving structural discrimination."

When he was asked at the start of his campaign about policies targeting gender inequality, Lee responded: "Why do you keep dividing men and women? They are all Koreans."

After drawing critcism, the DP acknowledged that women still "faced structural discrimination in many areas". And it pledged to tackle inequality for women with more resources at every level.

During his presidential bid in 2022, Lee was more vocal about the prejudice South Korean women encounter, seeking their votes in the wake of high-profile sexual harassment scandals in his party.

He had promised to put women in top positions in the government and appointed a woman as co-chair of the DP's emergency committee.

"It's evident that the DP is focusing significantly less on young women than they did in the [2022] presidential election," Ms Kim says.

Prof Go believes it's because Lee "lost by a very narrow margin" back then. So this time, he is "casting the widest net possible" for votes. "And embracing feminist issues is not a good strategy for that."

That stings for young women like Saeyeon, especially after the role they played in the protests calling for Yoon's impeachment: "Our voices don't seem to be reflected in the [campaign] pledges at all. I feel a bit abandoned."

The ruling party's Kim Moon-soo, who served in Yoon's cabinet as labour minister, has emphasised raising birth rates by offering more financial support to parents.

But many women say rising costs are not the only obstacle. And that most politicians don't address the deeper inequalities - which make it hard to balance a career and family - that are making so many women reconsider the usual choices.

The Ministry of Gender Equality and Family, which Yoon had wanted to shut down, has also re-emerged as a sticking point.

Lee has vowed to strengthen the ministry, while Kim says he will replace it with a Ministry of Future Youth and Family.

The ministry already focuses on family services, education and welfare for children. Just under 7% of its total funding, which is about 0.2% of the government's annual budget, goes towards improving equality for women. But Prof Go says the ministry was "politicised by Yoon and has since been weaponised".

"The ministry itself is not huge but it's symbolic… abolishing it would show that gender equality is unimportant."

It's also the target of a third candidate, 40-year-old Lee Jun-seok, a former leader of Yoon's party, who has since launched his own Reform Party.

Although trailing Kim in polls, Lee Jun-seok has been especially popular with many young men for his anti-feminist views.

Earlier this week, he drew swift outrage after a presidential debate in which he said: "If someone says they want to stick chopsticks in women's genitals or some place like that, is that misogyny?"

He said the "someone" was frontunner Lee Jae-myung's son, who he claimed made the comment online, an allegation which the Lee camp has sidestepped, apologising for other controversial posts.

But watching Lee Jun-seok say that on live TV "was genuinely terrifying," Byunghui says. "I had the scary thought that this might boost incel communities."

Saeyeon describes "anger and even despair" sinking the "hopes I had for politics, which weren't that great to begin with".

She believes his popularity "among certain sections of young men is one of the "significant repercussions" of South Korea "long neglecting structural discrimination" against women.

The only candidate to address the issue, 61-year-old Kwon Young-gook, didn't fare well in early polling.

"I'm still deliberating whether to vote for Lee Jae-myung or Kwon Young-gook," Saeyeon says.

While Kwon represents her concerns, she says it's smart to shore up the votes for Lee because she is "much more afraid of the next election, and the one after that".

She is thinking about Lee Jun-seok, who some analysts believe could eat into the votes of a beleagured PPP, while appealing to Yoon's base: "He is in the spotlight and as the youngest candidate, he could have a long career ahead."

That is all the more reason to keep speaking out, Byunghui says. "It's like there is dust on the wall. If you don't know it's there, you can walk by, but once you see it, it sticks with you."

It's the same for Jinha who says things can "never go back to how they were before Yoon declared martial law".

That was a time when politics felt inaccessible, but now, Jinha adds, it "feels like something that affects me and is important to my life".

She says she won't give up because she wants to be free of "things like discrimination at work… and live my life in peace".

"People see young women as weak and immature but we will grow up - and then the world will change again."
