===Post-National Front Years===

During the post-National Front years, the Colombian Government made efforts to negotiate a peace with the persistent guerrilla organizations that flourished in Colombia's remote and undeveloped rural areas. In 1984, President Belisario Betancur, a Conservative, negotiated a cease-fire with the Revolutionary Armed Forces of Colombia (FARC) and the Democratic Alliance/M-19 (M-19) that included the release of many imprisoned guerrillas. The National Liberation Army (ELN) rejected the government's cease fire proposal at that time. The M-19 pulled out of the cease-fire when it resumed fighting in 1985. The army suppressed an M-19 attack on the Palace of Justice in Bogota in November 1985, during which 115 people were killed, including 11 Supreme Court justices. The government and the M-19 renewed their truce in March 1989, which led to a peace agreement and the M-19's reintegration into society and political life. The M-19 was one of the parties that participated in the process to enact a new constitution (see below), which took effect in 1991. The FARC ended the truce in 1990 after some 2,000-3,000 of its members who had demobilized had been murdered.

A new constitution in 1991 brought about major reforms to Colombia's political institutions. While the new constitution preserved a presidential, three-branch system of government, it created new institutions such as the Inspector General, a Human Rights Ombudsman, a Constitutional Court and a Superior Judicial Council. The new constitution also reestablished the position of Vice President. Other significant constitutional reforms provide for civil divorce, dual nationality and the establishment of a legal mechanism ("tutela") that allows individuals to appeal government decisions affecting their constitutional rights. The constitution also authorized the introduction of an accusatory system of criminal justice that is gradually being instituted throughout the country, replacing the previous written inquisitorial system. A constitutional amendment approved in 2005 allows the president to hold office for two consecutive 4-year terms.

Colombian governments have had to contend with the combined terrorist activities of left-wing guerrillas, the rise of paramilitary forces in the 1990s and the drug cartels. Narco-terrorists assassinated three presidential candidates during the election campaign of 1990. After Colombian security forces killed Medellin cartel leader Pablo Escobar in December 1993, indiscriminate acts of violence associated with his organization abated as the "cartels" were broken into multiple and smaller trafficking organizations that competed against each other in the drug trade. Guerrillas and paramilitary groups also entered into drug trafficking as a way to finance their military operations.
