The Bicesse Accords ended the civil war in 1991 and saw the introduction of multi-party democracy. General elections were held in 1992, with the President being elected by the public for the first time. The MPLA won 129 of the 220 seats in the National Assembly, whilst UNITA emerged as the main opposition party with 70 seats. José Eduardo dos Santos of the MPLA and Jonas Savimbi of UNITA received the most votes in the first round of the presidential elections, but Savimbi claimed the election had been rigged, despite United Nations observers stating that they had been mostly free and fair. He refused to participate in the runoff, and restarted the civil war.
