In 2006, the then-president of Italy declared his country to be "the world's greatest cultural power." With Ruling Culture, Fiona Greenland traces how Italy came to wield such extensive legal authority, global power, and cultural influence-from the nineteenth century unification of Italy and the passage of novel heritage laws, to current battles with the international art market. Today, Italy's belief in its cultural superiority is evident through interactions between citizens, material culture, and the state-crystallized in the Art Squad, the highly visible military-police art protection unit. Greenland reveals the contemporary actors in this tale, taking a close look at the Art Squad and state archaeologists on one side and unauthorized excavators, thieves, and smugglers on the other. Drawing on years in Italy interviewing key figures and following leads, Greenland presents a multifaceted story of art crime, cultural diplomacy, and struggles between international powers.
