Roberto D'Aubuisson Arrieta (23 August 1943 – 20 February 1992) was a neo-fascist Salvadoran soldier, 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 El Salvador's Constituent Assembly from 1982 to 1983. He was a candidate for President in 1984, losing in the second round to former President of the Junta José Napoleón Duarte. After ARENA's loss in the 1985 legislative elections, he stepped down in favor of Alfredo Cristiani and was awarded the honorary post of party president for life. He was named by the UN-created Truth Commission for El Salvador as having ordered the assassination of then-Archbishop Óscar Romero in 1980. Early life D'Aubuisson was born to Roberto d'Aubuisson Andrade, a salesman of French roots, and Joaquina Arrieta Alvarado, a career civil servant, in Santa Tecla, La Libertad Department, El Salvador, on 23 August 1943. He graduated from the national military academy in 1963. He was part of La Tandona, the class of 1966 at the Captain General Gerardo Barrios Military School. In 1972, he was trained in communications at the School of the Americas, a United States Department of Defense Institute that provides military training to government personnel in US-allied Latin American nations. After completing his studies at the Institute, he subsequently became a member of the Salvadoran military intelligence. Death squads D'Aubuisson involved himself in death squad activity while in the military, and he became associated with the second death squad to emerge in El Salvador in the mid–1970s, called the White Warriors Union. In October 1979, after a group of progressive officers deposed the government of Carlos Humberto Romero in a coup d'état and established the Revolutionary Government Junta (JRG, 1979–1982), D'Aubuisson was forced out of military service for his death squad connections, although he continued working for senior military commanders secretly. D'Aubuisson was regularly featured on Salvadoran television denouncing alleged traitors and Communists, who were then murdered shortly afterwards by death squads. On 7 May 1980, six weeks after the assassination of Óscar Romero, D'Aubuisson and a group of civilians and soldiers were arrested on a farm. The raiders found weapons and documents identifying D'Aubuisson and the civilians as death squad organizers and financiers, and of planning a coup d'état to depose the JRG. D'Aubuisson was soon released from prison, after 8 of the 14 military garrison
