 Through the efforts of Las Casas's missionaries the so-called "Land of War" came to be called "Verapaz", "True Peace".Las Casas's strategy was to teach Christian songs to merchant Indian Christians who then ventured into the area.In this way he was successful in converting several native chiefs, among them those of Atitlán and Chichicastenango, and in building several churches in the territory named Alta Verapaz.
