Elections were held on April 29, 1979, under a new constitution. Jaime Roldós Aguilera was elected president, garnering over one million votes, the most in Ecuadorian history. He took office on August 10, as the first constitutionally elected president after nearly a decade of civilian and military dictatorships. In 1980, he founded the ''Partido Pueblo, Cambio y Democracia'' (People, Change, and Democracy Party) after withdrawing from the ''Concentración de Fuerzas Populares'' (Popular Forces Concentration) and governed until May 24, 1981, when he died along with his wife and the minister of defense, Marco Subia Martinez, when his Air Force plane crashed in heavy rain near the Peruvian border. Many people believe that he was assassinated by the CIA, given the multiple death threats leveled against him because of his reformist agenda, deaths in automobile crashes of two key witnesses before they could testify during the investigation, and the sometimes contradictory accounts of the incident.
