See main article: article and Colombian conflict. María La Baja has grown substantially in recent years as some 7000 people have moved into the town from the surrounding countryside, since 2000 when the FARC guerrilla group arrived in the hills nearby. According to reports[2] the FARC militants stole cattle. The situation deteriorated further when AUC paramilitaries began to battle FARC, catching civilians in the crossfire. However the security situation has improved more recently with the AUC bloc Heroes de los Montes de María giving up their weapons on July 14, 2005, under a national demobilization plan speared by the government of Álvaro Uribe. Marines have set up a base on the edge of the town.[2]
