Civilian Conservation Corps (CCC), established in 1933 by the U.S. Congress as a measure of the New Deal program. The CCC provided work and vocational training for unemployed single young men through conserving and developing the country's natural resources. At its peak in 1935, the organization had more than 500,000 members in over 2,600 camps. These were usually operated by the War Dept., but the men were not subject to military control. In 1939 the CCC was made part of the Federal Security Agency. Beginning in 1940, greater emphasis was placed on projects aiding national defense. Against President Franklin D. Roosevelt's request, Congress abolished the CCC in 1942.
