Costa Rican Civil War
The Costa Rican Civil War was the bloodiest event in 20th-century Costa Rican history. It lasted for 44 days (from 12 March to 24 April 1948), during which approximately 2,000 people are believed to have died. On 1 March 1948, the Legislative Assembly of Costa Rica, dominated by pro-government representatives, voted to annul the results of the presidential elections of 8 February, alleging that the triumph of opposition candidate Otilio Ulate over the ruling party's Rafael Ángel Calderón Guardia had been achieved by fraud. This triggered an armed uprising led by José Figueres Ferrer, a businessman who had not participated in the elections, against the government of President Teodoro Picado.
