Otilio Ulate Blanco

Luis Rafael de la Trinidad Otilio Ulate Blanco was a Costa Rican journalist and politician who served as the 31st President of Costa Rica from 1949 to 1953. His disputed election in 1948, whereby he was denied victory by the legislature in favor of Rafael Ángel Calderón Guardia, was the direct cause of José Figueres Ferrer's armed uprising of that year and the ensuing 44-day Costa Rican Civil War.
