Throughout the Cold War-era, the United States, along with its allies in the Americas, staged military interventions in several countries in North America, in an effort to contain communism. Military interventions of this nature include the Dominican Civil War in 1963, and the invasion of Grenada in 1983. As the Central American crisis unraveled in the late 1970s, several Central American states including El Salvador, Guatemala, and Nicaragua, saw civil wars and pro-communist revolutions erupt in their country. Various factions involved in those conflicts saw support from either the United States, or the Eastern Bloc, as the civil conflicts became proxies of the larger Cold War.
