The book Sur Profundo brings us closer to the cultural and political dynamics of the Mexico-Guatemala border. The testimonies and experiences of the Mayan peoples, which have been divided by national boundaries, remind us that this region is an open wound. From a historical-anthropological perspective, the author analyzes how the lives of the border indigenous Chujos, Kanjobales, Mam, Jacaltecos and Mochos, have been marked by the violence of campaigns of forced acculturation, by the economic violence of the reforms that force migration, and more recently by violence from organized crime.
