The Civilian Conservation Corps (CCC) was a public work relief program in the United States for unemployed men age 18-25, providing unskilled manual labor related to the conservation and development of natural resources in rural lands owned by federal, state and local governments from 1933 to 1942. As part of the New Deal of President Franklin D. Roosevelt (FDR), the CCC was designed to provide relief for young men in relief families who had a very hard time finding jobs during the Great Depression while implementing a general natural resource conservation program on public lands in every state and territory. Maximum enrollment reached 300,000 and in nine years some 2.5 million young men participated.
