대운동, or the "Great Movement," refers to a significant social and political movement in South Korea during the late 20th century. It aimed to promote democracy and human rights, particularly during the authoritarian regimes of the 1970s and 1980s. The movement involved various protests, demonstrations, and activism by citizens advocating for political reform and social justice. Key events associated with 대운동 include the Gwangju Uprising in 1980, where citizens rose against government oppression. This movement ultimately contributed to the establishment of a democratic government in South Korea, leading to greater political freedoms and civil rights for its citizens.
