Diego José Pedro Víctor Portales y Palazuelos (Spanish pronunciation: [ˈdjeɣo poɾˈtales]; June 16, 1793 – June 6, 1837) was a Chilean statesman and entrepreneur. As a minister of president José Joaquín Prieto's government, he played a pivotal role in shaping the state and politics in the 19th century, delivering with the Constitution of 1833 the framework of the Chilean state for almost a century. Portales' influential political policies included unitarianism, presidentialism and conservatism which led to the consolidation of Chile as a constitutional, authoritarian republic with the franchise restricted to upper class men.
