In his magisterial general history, Spain 1808–1939, Raymond Carr concluded that the failure of modern constitutional liberalism in Spain was above all “a political failure,” that is, more the consequence of political culture, status cleavages, and ideological divergence than the inevitable result of unadapted economic structures that could not support the formal political system. American reviewers such as Richard Herr and Gabriel Jackson were quick to take issue, arguing that political conflict in modern Spain had not been positively resolved because the economic structure had been too backward to permit it. They were obviously correct that the backwardness of the Spanish economy greatly hampered the civic processes of modern Spain—a point that Carr readily admitted in general. It is nonetheless largely true that modern Spanish politics have more often than not focused on issues of status and ideology rather than on specific conflicts over concrete economic issues.
