Background: Colombia was one of the three countries that emerged from the collapse of Gran Colombia in 1830 (the others being Ecuador and Venezuela). A 40-year insurgent campaign to overthrow the Colombian Government escalated during the 1990s, undergirded in part by funds from the drug trade. Although the violence is deadly and large swaths of the countryside are under guerrilla influence, the movement lacks the military strength or popular support necessary to overthrow the government. While Bogota continues to try to negotiate a settlement, neighboring countries worry about the violence spilling over their borders.
