Understanding the complexity of the ‘blood tax’: the Spanish conscription system

Social history has often examined ‘draft riots’ as expressions of public outrage against unfair conscription systems. In Spain, military service frequently provoked revolts, as it disproportionately affected underprivileged groups. Until 1912, redención en metálico (cash redemption) allowed wealthy individuals to avoid service, making Spain one of the last countries to abolish this system. Known as the ‘blood tax,’ it triggered riots, including the 1909 Barcelona uprisings. Despite its historical significance, Spanish conscription remains understudied. This article introduces Spain’s conscription system to an international audience and examines its historiographical treatment.
