Although Spain is an important member of the EU, relatively little is known about its economy and its interrelationship with political forces. This book, the first of its kind, offers a long-term view and analyzes this ever-changing relationship throughout the 20th century with its various upheavals such as the crisis of the democratic republic and the civil war in the 1930s, the long General Franco dictatorship from the 1940s until the 1970s and the subsequent transition to democracy. From the detailed studies of individual cases, specific companies as well as entrepreneurial organizations, a very diverse picture emerges, contradicting widespread simplistic interpretations of politico-economic linkages, which demonstrates both the pluralism of the economic interests as well as the complexity of their relationship to the political class.
