On October 10, 1951, the United States Congress established the Mutual Security Agency to strengthen America's allies in Europe through military assistance and economic recovery after determining this would be beneficial to America's long-term security. The agency superseded the Economic Cooperation Administration, which had only oversight over economic aid. The new agency was responsible for development and administration of those military and economic assistance programs not administered by the Technical Cooperation Administration.
Reorganization Plan No. 7 1953 (67 Stat. 641) abolished the Mutual Security Agency on August 1, 1953. The federal organization functions were transferred to the new Foreign Operations Administration.
