The Opposite of Containment: Electoral System Change in Argentina’s 1912 Democratic Transition

The traditional narrative of Europe’s first wave of democratization is that elites extended the franchise in response to revolutionary threats and reformed majoritarian electoral systems to limit rising working-class parties. This stylized account does not fit early twentieth-century South America, where democratization was driven by internal competition within incumbent parties, without strong working-class parties to contain. I study Argentina’s 1912 electoral reform that introduced elements of democracy (secret and compulsory voting) and simultaneously changed the electoral system from multi-member plurality to the limited vote. To study the motivations behind the electoral system change component of the reform package, I analyze expert surveys, legislative debates, and a 1911 public opinion poll. Granting representation to political minorities was regarded not as an electoral containment strategy to benefit incumbents, but a progressive measure to make opposition parties more competitive. An analysis of roll-call votes shows that legislators who supported the reform were those expecting to not be adversely affected.
