Espionage in the Vatican: Spies and Secrets in Rome

The Vatican's involvement in espionage and intelligence gathering is not a modern phenomenon born of Cold War necessities, but rather a continuation of practices that date back to the earliest days of the Catholic Church's temporal power. The papal states that once stretched across central Italy required sophisticated intelligence networks to survive in a world of competing city-states, foreign invasions, and shifting political alliances. The Church's need to protect its temporal interests while advancing its spiritual mission created a culture of secrecy and information gathering that would evolve and adapt to changing global circumstances throughout history.
