José Joaquín Casimiro Olañeta y Güemes (1795–1860) was a nephew of Pedro Antonio Olañeta who, after working for him, turned against his uncle in favor of Bolivian independence. He faced criticism as being two-faced or Machiavellian,[1] in part because the shift occurred in a matter of weeks.[2] He went on to serve as an advisor to Antonio José de Sucre. Casimiro opposed his land being linked in a nation with Argentina.[3]
Olañeta was President of the Bolivian constituent assembly in 1826. He was Minister of Finance of Peru from August 1837 to November 1837.[4] He served as the President of the Chamber of Senators of Bolivia in 1846 as well as a Peruvian representative in Chile.
