This article aims to contribute to the new electoral history by examining a specific practice of democracy, the voter registration card, known in Colombia as the citizenship card (cédula). After pursuing the themes of electoral reform and universal suffrage in a broader sense, the article outlines the card's history from its inception in 1929 to its role in the polemics over electoral corruption by the Conservative Party, which ranged over the period before the Violencia. While national-level politics are emphasised, the impact of the card at the municipal level also is suggested, as the critical link between the national and the local.
