This paper analyses the influence of political regimes on the level and economic composition of military expenditure in Spain over the long run. In contrast with the widely accepted negative relation between democracy and military spending, the paper suggests that democratic governments established in the late 1970s and early 1980s after Franco’s dictatorship had a positive influence on the military burden owing to the efforts to reorient the army towards international threats and to involve the armed forces with the newly democratic institutions. In addition, the analysis of military expenditure allows us to conclude that the international orientation of democratic military policies took place along with financial efforts to obtain a capital-intensive army to confront international military threats.
