Jimmy Carter

While in office, Jimmy Carter brokered historic peace deals and treaties. From the 1980s on, he worked tirelessly for conflict resolution around the globe through The Carter Center, where he engaged in mediation in Ethiopia, Eritrea, North Korea, Liberia, Haiti, Bosnia, Venezuela, Nepal and the Middle East, among many other countries and regions. Under his leadership, The Carter Center has sent election observation missions to the Americas, Africa and Asia. They're also leading the fight against Guinea worm, on track to be the second human disease in history to be eradicated.

In 2002, Carter was awarded the Nobel Peace Prize "for his decades of untiring effort to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development." He was a member of the Elders, a group of independent global leaders working for peace and human rights.
