Dubbed ‘the Impaler’ by his contemporaries, Vlad III Dracula (c. 1431–76), was accused of the slaughter of between 40,000 and 100,000 individuals, 20,000 of them allegedly impaled at the Wallachian capital Targovişte. Although historians have often considered these figures inflated, none of the numerous studies dedicated to the voivode of Wallachia have undertaken a methodical evaluation of the extent of this exaggeration. This article takes up this historiographical challenge by examining all available documentation. In so doing, it provides a full reassessment of the practice of impalement in fifteenth-century south-eastern Europe. Contrary to assumptions of previous scholarship, Vlad’s use of impalement was influenced simultaneously by pre-existing Hungarian and Ottoman practices. Quantitative analysis shows that only 7–10 per cent of the impalements claimed by sources can be considered plausible and proposes a new data-driven estimation of Vlad’s impaled victims. Finally, a comparison with other rulers shows that, while Vlad ordered collective impalements more frequently, the average number of victims per impalement was similar to that elsewhere in south-eastern Europe.
