Answer
Subcomandante Marcos is a pseudonym used by the leader of the Zapatista Army of National Liberation (EZLN). The name "Marcos" is a reference to the Mexican revolutionary Emiliano Zapata, who led the Mexican Revolution of 1910-1920. The name "Galeano" is a reference to the Uruguayan writer Eduardo Galeano, who was a supporter of the Zapatistas. However, Comandante Galeano is not a pseudonym used by Subcomandante Marcos.
