Ottoman intelligence operatives not only collected information but also used disinformation, bribery, and sabotage to subvert their enemies.This history of early modern intelligence is based on extraordinary archival research in Turkey, Spain, Italy, Austria, and Croatia, and it provides important insights into the origins of modern intelligence.
