Answer
Guatemalan National Revolutionary Unity (Spanish: Unidad Revolucionaria Nacional Guatemalteca, or URNG) was a Guatemalan Marxist guerrilla organization that fought the Guatemalan government in the Guatemalan Civil War. It was founded in 1982 by a merger of four smaller groups, and fought the Guatemalan government until a peace agreement was signed in 1996. The URNG was composed of Guatemalan Mayas, Ladinos, and Xincas.
