Francisco Javier Arana, Guatemalan Army colonel and briefly Guatemalan head of state (died 1949)

Francisco Javier Arana Castro was a Guatemalan military leader and one of the three members of the revolutionary junta that ruled Guatemala from 20 October 1944 to 15 March 1945 during the early part of the Guatemalan Revolution. A major in the Guatemalan army under the dictator Jorge Ubico, he allied with a progressive faction of the army to topple Ubico's successor Federico Ponce Vaides. He led the three-man junta that oversaw the transition to a democratic government, although he was personally reluctant to allow the elected President Juan José Arévalo to take office in 1945. He served as the Chief of the Armed Forces in the new government until 1949. On 18 July 1949 he was killed in a shootout with supporters of the Arévalo government after he threatened to launch a coup.
