A crowd of South ­Koreans, jubilant at the impeachment of their president, Park ­Geun-hye, over a corruption scandal, took to the streets of Seoul on Saturday night to call for her arrest and imprisonment.

The crowds were much smaller than the huge candlelight rallies that contributed to her ouster, but the sense that this was a historic moment was clear. Thirty years after they protested to bring democracy to their country, South Koreans had protested to bring about the peaceful removal of a president.

“The Republic of Korea is a democratic nation,” people sang in the central Gwanghwamun Plaza, waving signs that said ­“Arrest Park Geun-hye” and “Go to prison.”

Some people took selfies in front of a replica jail cell containing cardboard cutouts of Park and the others implicated in the scandal, while others snacked on specially packaged “prison bread.”
