José Napoleón Duarte Fuentes was a Salvadoran politician who served as President of El Salvador from 1 June 1984 to 1 June 1989. He was mayor of San Salvador before running for president in 1972. He lost, but the election is widely viewed as fraudulent. Following a coup d'état in 1979, Duarte led the subsequent civil-military Junta from 1980 to 1982. He was then elected president in 1984, defeating ARENA party leader Roberto D'Aubuisson.

Roberto D'Aubuisson Arrieta was a Salvadoran military officer, neo-fascist politician, and death squad leader. In 1981, he co-founded and became the first leader of the far-right Nationalist Republican Alliance (ARENA) and served as president of the Legislative Assembly from 1982 to 1983. He was a presidential candidate for 1984 presidential election, losing in the second round to José Napoleón Duarte, the former president of the Revolutionary Government Junta. After ARENA's loss in the 1985 legislative elections, D'Aubuisson stepped down in favor of Alfredo Cristiani and was designated as the party's honorary president for life. D'Aubuisson was named by the United Nations' Truth Commission for El Salvador as having ordered the assassination of Óscar Romero, the archbishop of San Salvador in 1980.
