General Fernando Romeo Lucas García (4 July 1924 – † 27 May 2006) was the 37th President of Guatemala from July 1, 1978 to March 23, 1982. He was elected as Institutional Democratic Party candidate (with the support of the Revolutionary Party). Elections for his presidency were fraud-ridden. During Lucas García's regime, tensions between the radical left and the government increased. The military started to murder political opponents while counterinsurgency measures further terrorized populations of poor civilians.
