National Intelligence Service (South Korea) 大韩民国国家情报院
（重定向自KCIA）
The National Intelligence Service (NIS) (대한민국국가정보원, 국정원) is the chief intelligence agency of South Korea. The agency was officially established in 1961 as the Korean Central Intelligence Agency (KCIA) (중앙정보부), during the rule of President Park Chung-hee's military Supreme Council for National Reconstruction, which displaced the Second Republic of South Korea. The original duties of the KCIA were to supervise and coordinate both international and domestic intelligence activities and criminal investigation by all government intelligence agencies, including that of the military. The agency's broad powers allowed it to actively intervene in politics.
