The Peace Corps traces its roots and mission to 1960, when then Senator John F. Kennedy challenged students at the University of Michigan to serve their country in the cause of peace by living and working in developing countries. From that inspiration grew an agency of the federal government devoted to world peace and friendship.

Since that time, 200,000+ Peace Corps Volunteers have served in 139 host countries to work on issues ranging from AIDS education to information technology and environmental preservation.

Today's Peace Corps is more vital than ever, working in emerging and essential areas such as information technology and business development, and contributing to the President's Emergency Plan for AIDS Relief. Peace Corps Volunteers continue to help countless individuals who want to build a better life for themselves, their children, and their communities.
