This report examines the societal changes in South Korea over the past 40 years or 20 years from the perspective of the disability rights movement, and urges the collective effort to shape the future of Korean society in the next 20 years. Noting that the impact of the disability rights movement has materialized in the form of disability rights legislation, the report describes their relationship in major phases. The report highlights that the Disabilities Rights Act and the Amendment Bill on Welfare of the Disabled proposed by the 21st National Assembly mark a new phase in the 20- to 40-year history of disability rights legislation, and predicts that the next 20 years of Korean society will be determined by how these bills are passed and implemented.
