The National Liberation Forces (Spanish: Fuerzas de Liberación Nacional, FLN) were an insurgent group in Mexico.
It was founded in 1969 by a group of young regiomontanos led by César Yáñez Muñoz, integrating the members of an old dissolved organization called the Mexican Insurgent Army.
Some EZLN leaders have argued that the vanguardist and Marxist–Leninist orientation of the FLN failed to appeal to indigenous locals in Chiapas, leading former members of the FLN in the EZLN to ultimately opt for a libertarian socialist and neozapatista outlook after interacting with local communities.
[1][2] The National Liberation Forces were established in August 1969, the founders were mainly students of the University of Nuevo León and former members of the dissolved Mexican Insurgent Army, who briefly operated in Chiapas.
The storming of El Chilar led to the self-dissolution of the National Liberation Forces, who continued their agitation underground.
