The Central American crisis began in the late 1970s, when major civil wars and communist revolutions erupted in various countries in Central America, causing it to become the world's most volatile region in terms of socioeconomic change. In particular, the United States feared that victories by communist forces would cause South America to become isolated from the United States if the governments of the Central American countries were overthrown and pro-Soviet communist governments were installed in their place. During these civil wars, the United States pursued its interests by supporting right-wing governments, who were supported by the elite classes, against left-wing guerrillas, who were supported by the peasant and working class.[1]
