Subcomandante Marcos was the nom de guerre used by Rafael Sebastián Guillén Vicente (born (1957-06-19)19 June 1957), Mexican insurgent and former leader and spokesman of the Zapatista Army of National Liberation (EZLN) during the Chiapas conflict. Marcos has used several other pseudonyms; he referred to himself as Delegate Zero during the 2006 Mexican Presidential Campaign, and in May 2014 announced that Subcommandante Marcos "no longer exists," adopting the name Subcomandante Galeano instead.Born in Tampico, Tamaulipas, Marcos earned a degree in sociology and a master's degree in philosophy from the National Autonomous University of Mexico (UNAM), and taught at the Autonomous Metropolitan University (UAM) for several years during the early 1980s. During this time he became increasingly involved with a guerrilla group known as the National Liberation Forces (FLN), before leaving the university and moving to Chiapas in 1984. Wikipedia
