Pío Romero Bosque
Pío Romero Bosque (1860 – 10 December 1935) was a Salvadoran politician who served as president of El Salvador from 1 March 1927 until 1 March 1931. He also served as the vice president of Alfonso Quiñónez Molina from 1 March 1923 to 1 March 1927.
He is reputed to be one of the few, if not the only, Salvadoran president who was able to strike a political balance in government during his administration. This balance is often known as the "natural mix" – a balance between concession to demands of the various components of society and repression of the same in a given country. He was a scion of the Meléndez–Quiñónez "dynasty", who, rather than impose his own heir as president, allowed a democratization of the country with its first free elections in 1931, won by Arturo Araujo.
