From the 1970s on, some 100,000 people set up homes in this rainforest area, with many being recognized as "ejidos", or communal land-holding organizations. These migrants included Tzeltals, Tojolabals, Ch'ols and mestizos, mostly farming corn and beans and raising livestock. However, the government changed policies in the late 1980s with the establishment of the Montes Azules Biosphere Reserve, as much of the Lacandon Jungle had been destroyed or severely damaged. While armed resistance has wound down, the Zapatistas have remained a strong political force, especially around San Cristóbal and the Lacandon Jungle, its traditional bases. Since the Accords, they have shifted focus in gaining autonomy for the communities they control.
