The Central Intelligence Agency was created in 1947 with the signing of the National Security Act by President Harry S. Truman. The act also created a Director of Central Intelligence (DCI) to serve as head of the United States intelligence community; act as the principal adviser to the President for intelligence matters related to the national security; and serve as head of the Central Intelligence Agency. The Intelligence Reform and Terrorism Prevention Act of 2004 amended the National Security Act to provide for a Director of National Intelligence who would assume some of the roles formerly fulfilled by the DCI, with a separate Director of the Central Intelligence Agency.
