Óscar Únzaga

Óscar Únzaga de la Vega (19 April 1916 – 19 April 1959) was a Bolivian political figure and rebel. Most significantly, he founded the Bolivian Socialist Falange (FSB) movement in 1937, and ran for President in the 1956 elections, when his party became the main opposition movement to the Movimiento Nacionalista Revolucionario (MNR).

In 1959, Únzaga was one of fifty people who died during an attempted coup by the FSB. Government forces reported that he killed himself, but supporters disputed the official account and claimed that he was assassinated.
