Note on archival sources: There were 113 volumes of correspondence in the Archivo de la Gobernación de Antioquia for the period from 1947 to 1953. None of the material in the archive is indexed, nor were all of the volumes numbered. The absence of a volume number in the citations therefore is not an oversight. The material contained in the Archivo de la Gobernación, moreover, was not always in chronological order. Thus, it was possible for material from say, March 1947, to be included in different volumes of the 1947 correspondence or sometimes even in volumes for the correspondence of another year.
