Presidential elections were held in Colombia on 5 May 1946, pitching the Colombian Conservative Party against two different Colombian Liberal Party candidates.[1] The Liberals received more votes combined, but due to their division the result was a victory for Mariano Ospina Pérez of the Conservative Party, who received 41.4% of the vote.[2] One of the Liberal candidates, Gabriel Turbay, was also supported by the Social Democratic Party.[2]
Two years after the election, the second Liberal Party candidate, Jorge Eliécer Gaitán Ayala, was assassinated. This in turn sparked a ten-year civil war known as La Violencia.[2]
