The Peace Corps has been a leader in international development and citizen diplomacy for more than 50 years across more than 139 countries. In an increasingly interdependent world, we tackle challenges that know no borders—such as Education, health education around pandemic disease, agriculture & food security, environment & climate change, small business development, and youth development. Although times have changed since the Peace Corps' founding in 1961, the agency's mission—to promote world peace and friendship—has not. Today, the Peace Corps is more vital than ever, working in collaboration with partner organizations and using cutting-edge technologies and well-tested best practices to enhance impact.
