African leaders began a series of peace talks between the warring factions following a request by the United Nations Secretary General Boutros Boutros-Ghali for them to intervene in the humanitarian crisis. Talks were initiated under the aegis of former Tanzanian President Julius Nyerere in 1995; following his death, South African President Nelson Mandela took the helm. As the talks progressed, South African President Thabo Mbeki and United States President Bill Clinton also lent their respective weight.
