"'What have the Spaniards ever done for us?' imperial subjects may have asked, plotting rebellion. 'Aqueducts?' One may have ventured. 'Okay, aqueducts. What else?' 'Appeals courts?' 'Right! Appeals courts. And?' 'Well, the mails?' 'Okay. So there are the aqueducts, the appeals courts, the royal mail. But really, what have the Spaniards ever done for us?' 'Hospitals?' 'The transoceanic fleet system?' 'Defensive fortifications?' 'Arched bridges?' 'A standardized writing system?' One gets the idea. Certain to spark heated discussions like this one, How the Spanish Empire was Built offers a comprehensive defense of Spanish logistical ingenuity, a neo-Roman project of truly global dimensions.

Known mostly to Spanish historians of science and engineering until now, the logistical stuff of empire, what made it function day-by-day for so long despite the tyranny of distance, the temptations of corruption, and the relentless downward tug of entropy, has remained obscure to most Anglophone readers. In an age obsessed with global supply chains, instant communications, and global epidemics, there is much to be learned from predecessors who first encircled the world, for better or worse. The authors say this is simply a book about the 'scaffolding of empire,' but it is about much more. It is a provocation.".
