Housed in an old prison, the Archivo General de la Nación (or AGN, General Archive of the Nation), is home for the historical memory of Mexico. Its origins date back to the late eighteenth century when a royal decree ordered the creation of an archive to preserve documentation from the Viceroyalty. Today, the documents at AGN are a genealogical treasure waiting to be discovered by a wider audience of researchers. In this presentation you will learn about how to navigate the archive, and some of the information you could find there.
