A chaebol (; Korean: [tɕɛ̝.bʌl] (listen)) is a large industrial conglomerate that is run and controlled by an owner or family in South Korea. A chaebol often consists of a large number of diversified affiliates, controlled by an owner whose power over the group often exceeds legal authority. The term is often used in a context similar to that of the English word "conglomerate". The term was derived from the Japanese. It was first used in English in 1984. There are several dozen large South Korean family-controlled corporate groups that fall under this definition.
The chaebol have also played a significant role in South Korean politics. In 1988, a member of a chaebol family, Chung Mong-joon, president of Hyundai Heavy Industries, successfully ran for the National Assembly of South Korea. Other business leaders also were chosen to be members of the National Assembly through proportional representation. Hyundai has made efforts to contribute to the thawing North Korean and South Korean relations, but not without controversy. Many South Korean family-run chaebols have been criticized for low dividend payouts and other governance practices that favor controlling shareholders at the expense of ordinary investors.
