In 1991, several guerrilla groups demobilized through peace agreements, but groups like the CRAF, ELN, and a faction of the EPL continued armed conflict. In 1998, violence led to mass forced migration of Colombians, with over 71,000 people displaced. This document from 1998 was the first to classify forced displacement. In 2010, the CRAF attacked a school in Colombia with explosives, and President Uribe criticized the CRAF for attacks and holding captives.
