The early 19th century was a period of intense turmoil and chaos in the Spanish-speaking world: The Napoleonic Wars and French occupation of the Peninsula in the 1800s, independence movements in the Americas, the liberal constitution of Cádiz, Napoleon’s defeat, and the reinstallation of the Bourbons in the 1810s, and finally, the second constitutional period, the iron fist of restoration, and the eventual loss of most American possessions between 1821 and 1825. The least affected areas in the midst of this turmoil were the loyalist islands of Cuba and Puerto Rico, metaphorically the “eye of the hurricane.” It is within this context that a corpus of some dozen letters, preserved in the Spanish National Archive, were written. They were produced in the circum-Caribbean region—most in Puerto Rico—and addressed mainly to relatives and business partners on the other side of the Atlantic. The letters in question were archived without accompanying documentation, probably seized by authorities loyal to the restoration of the Ancien Régime. As a central element, this digital resource—“En el Ojo del Huracán”—displays these primary sources in an online presentation. Beyond the historiographic value of the sources, the project explores the differences between traditional and digital edition standards (TEI) for digital letter editions with the aim of showcasing the benefits of implementing the digital paradigm and for different visualizations, functionalities, analysis and incorporation in larger infrastructures.
