An acronym for "Fuerzas Armadas Revolucionarias de Colombia", or the Revolutionary Armed Forces of Colombia. It is South America's largest revolutionary organization.
It was established in 1959, at the time of the Cuban Revolution. In 1964, it took armed action against the Columbian government with support from the Soviet Union.
Although the FAR signed a peace treaty with the government in 1984 and participated in political affairs for a time, violence continued, and the organization returned to guerilla activities.
The group grew 20,000 strong by the 1990s, and was feared for its involvement in the drug trade.
