Migration is in the news every day. Whether it be the plight of refugees fleeing Syria, or the outbreak of the Zika virus across Latin America, the modern world is fundamentally shaped by movement across borders. Migration, arising from the 2018 Darwin College Lectures, brings together eight leading scholars across the arts, humanities, and sciences to help tackle one of the most important topics of our time. What is migration? How has it changed the world? And how will it shape the future? The authors approach these questions from a variety of perspectives, including history, politics, epidemiology, and art. Chapters related to policy, as well as those written by leading journalists and broadcasters, give perspective on how migration is understood in the media, and engage the public more widely. This interdisciplinary approach provides an original take on migration, providing new insights into the making of the modern world.
