León Cortés Castro was a Costa Rican politician. He served as President of Costa Rica from 1936 to 1940. During his term he introduced new bank reforms, supported banana plantations in the South Pacific region, and established ports at Quepos and Golfito. His administration is often referred to as the "iron bars and cement administration" because of the various construction projects undertaken during his presidency, including the construction of the former International Airport of La Sabana. He was the last of a series of relatively conservative Presidents. He considered changes to allow him to pursue re-election as President, but ultimately backed down due to a Constitutional ban on consecutive terms. He was succeeded by Rafael Ángel Calderón Guardia, who ultimately broke with tradition and substantially increased the scope of the social state.
