Input: Question: What year was the defense minister born who overthrew Montt in 1983? Passage:Jose Efrain Rios Montt (; June 16, 1926 April 1, 2018) was a Guatemalan general, politician, and war criminal who served as President of Guatemala. Born in Huehuetenango, he was a dictator who took power as a result of a coup d'etat on March 23, 1982. He was overthrown by his defense minister, Oscar Humberto Mejia Victores, in another coup d'etat on August 8, 1983. In the 2003 presidential elections, Rios Montt unsuccessfully ran as the candidate of the Guatemalan Republican Front (FRG). In 2007 he returned to public office as a member of Congress, thereby gaining prosecutorial immunity. He was protected from a pair of long-running lawsuits alleging war crimes against him and a number of his former ministers and counselors during their term in the presidential palace in 198283. His immunity ended on January 14, 2012, with the end of his term in legislative office. On January 26, 2012, he appeared in court in Guatemala and was formally indicted for genocide and crimes against humanity.
