Portrait of Santiago de Liniers

Jacques de Liniers (July 25, 1753 – August 26, 1810) was a French officer in the Spanish military service, and a viceroy of the Spanish colonies of the Viceroyalty of the Río de la Plata. He is more widely known by the Spanish form of his name, Santiago de Liniers. He was popularly regarded as the hero of the reconquest of Buenos Aires after the first British invasion of the Río de la Plata, which led to his designation as viceroy, replacing Rafael de Sobremonte. Such a thing, the replacement of a viceroy without the King's direct intervention, was completely unprecedented. He was confirmed in office by Charles IV of Spain, and endured a second ill-fated British Invasion attempt and a mutiny that sought to replace him. He was replaced in 1809 by Baltasar Hidalgo de Cisneros, appointed as viceroy by the Junta of Seville, and retired from public activity. However, when the May Revolution took place, Liniers decided to come out of his retirement and organized a monarchist uprising in Córdoba. However, Liniers was defeated, captured, and executed without trial.
