The National Security Act of 1947 Is Enacted

By September 18, 1947

Congress enacts the National Security Act of 1947, which establishes the Central Intelligence Agency for the primary purpose of gathering intelligence. The CIA was preceded by the World War II Office of Strategic Services.

The act also gives the Director of Central Intelligence the responsibility for “protecting intelligence sources and methods from unauthorized disclosure.”
