The Office of Civil Defense (OCD) was originally established under the President as part of the Office of Emergency Preparedness. In 1961, it was transferred to the DoD. Later, in 1964, OCD was transferred to the Department of the Army. In 1972, it became the Defense Civil Preparedness Agency, again falling under DoD. Its functions were eventually transferred to the newly established Federal Emergency Management Agency in 1979, which is now part of the Department of Homeland Security.
