Abstract
This essay attempts to foster the importance for Puerto Rican historiography of the collection of the Spanish Foreign Affairs Ministry‘s Archive, specifically the documents and letters of the Spanish consuls in Puerto Rico, covering the period between 1899 and 1930 (although from First World War onwards the sequence becomes more erratic). Among the subjects that can be developed or restated with these documents we can mention the representation of Puerto Rican identities during the first third of the Twentieth-Century, as well as the relationship between Spanish and Puerto Rican power groups in the Island, the political and economic situation of the Spanish residents and the diversity of continuities and imperial traces that remained in Puerto Rico after more than four centuries of linkings with Spain‘s political structures. The essay also offers some research approaches and displays revealing fragments of some consular dispatches.
