Julio César Méndez Montenegro

Julio César Méndez Montenegro (November 23, 1915 – April 30, 1996) was the Revolutionary Party President of Guatemala from 1 July 1966 to 1 July 1970. The only civilian to occupy Guatemala's presidency during the long period of military rule between 1954 and 1986, Méndez was not allowed to act independently of the military and was seen as a puppet leader. He was the first cousin of César Montenegro Paniagua whose kidnapping, torture and murder during the Julio César Méndez presidency is rumored to have been undertaken with presidential sanction.
