Manuel María Orellana Contreras

Manuel María Orellana Contreras was a Guatemalan army officer and politician, and from 17 to 31 December 1930, de facto interim President of Guatemala, after leading a coup d'état that ended Baudilio Palma's interim presidency. Palma, in turn, had been appointed president only four days earlier, when president Lázaro Chacón González suffered a stroke and was forced to resign. At the time the coup took place, Orellana Contreras was commander of the San Rafael de Matamoros Fort in Guatemala City.
