Connecting past and present

Adrian Masters

Dr. Adrian Masters is a Postdoctoral Fellow at the University of Texas at Austin’s Institute for Historical Studies.

His research focuses on 16th century Spanish imperial bureaucracy, racial formations, and state knowledge. He is currently co-authoring a book with Jorge Cañizares-Esguerra, entitled The Radical Spanish Empire (under contract with Harvard University Press). He is also working on his own book, tentatively entitled Empire of Petitioners: Creating the Law in the 1500s Spanish Empire, and he has a forthcoming article in the August edition of the Hispanic American Historical Review, called ‘A Thousand Invisible Architects: Vassals, the Petition and Response System, and the Creation of Spanish Imperial Caste Legislation.’

In episode 17 of History Hub’s podcast series – ‘Kingdom, Empire and Plus Ultra: conversations on the history of Portugal and Spain, 1415-1898‘ – Dr. Masters and series host Dr. Edward Collins discuss the petition and response system. The system has been central to Adrian’s work on Spanish imperial bureaucracy, part of what he calls a ‘responsive regime’ – that is, a largely passive state that relied almost entirely on reports and requests of a huge range of subjects.

This arrangement enabled the participation of almost anyone in the imperial system from the bottom up, and constructed the profoundly productive bureaucratic and social mechanics of the Spanish Empire, which incubated phenomena we associate with modernity today. The podcast is now available on iTunes and Soundcloud.
