Luis Arturo González López

Luis Arturo González López (21 December 1900 – 11 November 1965) was a Guatemalan attorney and politician who served as the acting President of Guatemala from 27 July 1957 to 24 October 1957. He became president after the assassination of Carlos Castillo Armas, under whom he was designated as first in the presidential line of succession by Congress.

Supporters of Castillo Armas were considering forming a military junta and seizing power, but were dissuaded by Edwin J. Sparks. the U.S. ambassador to Guatemala. The U.S. government preferred to preserve a facade of democracy, rather than have Guatemala revert to a blatant dictatorship. Elections were held in October 1957, complicated by pressure from the U.S. government, the government of Dominica, and the army.

The centrist Miguel Ortiz Passarelli won a plurality in these elections, but supporters of Miguel Ydígoras Fuentes, who had also been a candidate in the election, rioted. The Guatemalan government declared martial law for a period of 30 days. On 24 October, a group of 80 military officers marched into the Presidential palace and replaced González López with a three-person junta led by army Colonel Óscar Mendoza Azurdia. New elections were held in January 1958. Ydígoras Fuentes comfortably won this election and seized power for himself soon after.
