The House of Representatives (Korean: 민의원; Hanja: 民議院) was the lower house of the National Assembly of South Korea during its First and Second Republics.^[1] The House of Representatives was established by the Constitution of the First Republic of Korea, which established a bicameral legislature. However, as the House of Councillors was never established during the First Republic, the House of Representatives acted as the only house in a unicameral legislature until the House of Councillors was actually established in the Second Republic.
