"I came here with hope in my heart, believing we would win.  It's so unfair," 64-year-old Won Bog-sil told BBC Korean from the rally, where thousands had gathered in support of Yoon. These scenes were live streamed to thousands more on YouTube - a platform popular with not just Yoon's supporters but the president himself. A disgraced Yoon is now stripped of his power, but he leaves behind an ever more divided South Korea. December 2024, Yoon's shock martial law declaration cost him the confidence of much of the country. But among his supporters, his ongoing legal troubles have only further buttressed the image of a wronged saviour.

Many of them echo narratives peddled by influential right-wing YouTubers who support Yoon: that martial law was necessary to protect the country from pro-North Korea opposition lawmakers and a dangerously powerful opposition, and that Yoon's conservative party was a victim of election fraud. All this has culminated in a fringe movement that has become both more energised and extreme, spilling out from behind computer screens onto the streets. "Stop the Steal" signs have become a fixture at pro-Yoon rallies - co-opted from supporters of US President Donald Trump, whose own political career has been helped by a network of conservative YouTubers.
