Machel's successor Joaquim Chissano implemented sweeping changes in the country, starting reforms such as changing from Marxism to capitalism and began peace talks with RENAMO. The new constitution enacted in 1990 provided for a multi-party political system, market-based economy, and free elections. The civil war ended in October 1992 with the Rome General Peace Accords, first brokered by the Christian Council of Mozambique (Council of Protestant Churches) and then taken over by Community of Sant'Egidio. Peace returned to Mozambique, under the supervision of the ONUMOZ peacekeeping force of the United Nations.
