Spanish Agriculture: The Long Siesta, 1765–1965 is the first major study in English of Spanish agrarian history. James Simpson examines how traditional agriculture responded to population growth and the integration of commodity markets, emphasising both Spain’s regional variations and its context in Europe. Using statistical data as well as his wide knowledge of the recent secondary literature, Simpson argues that decisive changes in farming techniques only occurred at the start of this century. He rejects arguments that slow growth can be explained by poor resources or inefficient farmers. Indeed, farmers were quick to change when they had market opportunities, but development was interrupted by the Spanish Civil War and subsequent short-sighted government policies, only resuming in the 1950s. This comprehensive study will be of relevance to students and scholars of historical geography and agrarian history, as well as economic history.
