Which country is known for having a civil war from 1979-1992 that pushed many migrants to the U.S.?

The country known for experiencing a civil war from 1979 to 1992 that resulted in significant migration to the U.S. is El Salvador. During this conflict, widespread violence and human rights abuses led many Salvadorans to flee their homes in search of safety and better living conditions. The civil war was marked by the struggle between the government forces and leftist guerillas, causing substantial turmoil and loss of life. As a result, a large number of Salvadorans sought refuge in the United States, contributing to the substantial Salvadoran diaspora.

While other Central American countries also experienced conflict and resulted in some migration, El Salvador's civil war during this specific timeframe is particularly notable for its impact on migration patterns, making it the appropriate answer to the question.
