National Intelligence Service

The National Intelligence Service (NIS; Korean: 국가정보원, 국정원) is the chief intelligence agency of South Korea. The agency was officially established in 1961 as the Korean Central Intelligence Agency (KCIA; Korean: 중앙정보부), during the rule of President Park Chung Hee's military Supreme Council for National Reconstruction, which displaced the Second Republic of Korea. The original duties of the KCIA were to supervise and coordinate both international and domestic intelligence activities and criminal investigations by all government intelligence agencies, including that of the military. The agency's broad powers allowed it to actively intervene in politics. Agents undergo years of training and checks before they are officially inducted and receive their first assignments.
