The FARC was created in 1964 as the military wing of the local Communist Party to fight to build the "New Colombia" - a society of social justice and equality. The ranks of the group consisted of up to 20,000 fighters.
The authorities and the rebels spent a long time negotiating peace, which ended with the signing of a peace agreement. In 2017, on the basis of the FARC, the Common Revolutionary Alternative Force political party was officially created.
