Massimo Livi Bacci is a renowned Italian demographer whose work has united historical and statistical approaches to generate new insights into migration, mortality and population. Currently Professor of Demography at the University of Florence, Livi Bacci is renowned for the ambitious scope of his work, which covers topics ranging from the sixteenth-century hunt for the mythical El Dorado to the world history of migration. His strongly interdisciplinary approach has allowed him to examine with great subtlety the role of a complex interplay of cultural, economic, social and political factors in determining the history of the world’s population, its growth, movement and decline. His recent work on migration has skilfully illustrated the positive role that migration has played in economic development and the questionable political dynamics of state control of borders. Polity has published several of his books, including Conquest, El Dorado in the Marshes and A Short History of Migration.
