Based on a wide range of archival sources, this book analyses the response of the most peripheral country in Western Europe, Franco's Spain, to the challenges of increasing economic interdependence from the end of World War II to the establishment of the EEC, 1945-57. In so doing, the author sheds new light on the fundamental question of the survival of the Franco regime and stimulates further discussion on the external factors responsible for Spain's pattern of economic growth after 1945.
