Colombian conflict is one of the longest worldwide internal conflicts during 20th century. Although this conflict has taken place in rural and metropolitan areas, its repercussion has been more evident over rural sectors. Confrontations between governmental forces and illegal armed groups have generated internally displaced people especially on the south of Colombia.
