The 2016-2017 South Korean protests, also known as the Candlelight Revolution, were a series of large-scale demonstrations against then-President Park Geun-hye. The protests began in October 2016 after allegations surfaced that she was involved in a corruption scandal involving her close friend, Choi Soon-sil. Millions of South Koreans took to the streets, demanding her resignation and accountability. The movement gained momentum over several months, culminating in a significant protest on December 3, 2016, where over a million people participated. In March 2017, the Constitutional Court upheld her impeachment, leading to her removal from office. The protests are seen as a pivotal moment in South Korea's democratic development.
