The Miracle on the Han River refers to the period of rapid economic growth in South Korea, following the Korean War (1950–1953), during which South Korea transformed from a developing country to a developed country. The rapid reconstruction and development of the South Korean economy during the latter half of the 20th century was accompanied by events such as the country's successful hosting of the 1988 Summer Olympics and its co-hosting of the 2002 FIFA World Cup, as well as the ascension of family-owned conglomerates known as chaebols, such as Samsung, LG, and Hyundai.
