The "4.19 혁명" (April 19 Revolution) was a significant student-led uprising in South Korea that took place in 1960. It aimed to protest against the corrupt government of President Syngman Rhee, who had been in power since the Korean War. The movement was sparked by the rigged presidential election in March 1960, leading to widespread demonstrations demanding democratic reforms. The revolution resulted in the resignation of Rhee on April 26, 1960, and marked a pivotal moment in South Korea's struggle for democracy. It inspired future movements and laid the groundwork for subsequent democratic developments in the country.
