Joaquín Madariaga (1799 in Corrientes – 1848) was a soldier and Argentine politician. Madariaga was Governor of the Corrientes Province and leader of the provinces resistance against the national government of Juan Manuel de Rosas. The Revolution of Madariaga Madariaga was a soldier from a young age in the city of Buenos Aires, and participated in the acts known as the 'Anarchy of 1820'. He returned in 1824 to Corrientes, where he worked as a lawyer without having qualified as one and became a judge in the provincial capital. Years later he relocated to Curuzú Cuatiá, where he dedicated himself to rural work. He was deputy in the Provinivial Legislature during the governorship of Genaro Berón de Astrada and after the governor's death he supported the revolution that overthrew the federal governor Romero. Pedro Ferré named Joaquín's brother, Juan Madariaga, as commander of Mercedes and Curuzú Cuatiá. He helped Juan Lavalle form the army with which he conducted the campaign of Entre Rios in 1840. Upon the arrival of José Maria Paz in Corrientes, he participated in the campaign against the first invasion of the Governor of Entre Ríos, Pascual Echagüe. Alongside his brother, Juan fought in the Battle of Caaguazú, Paz's most brilliant victory. In 1842 they were defeated in the Battle of Arroyo Grande. They retreated toward Corrientes but they were denied by the Ferré government, forcing them to retreat to their ranches to save their family and property. From there they fled to Brazil, residing for some time in Alegrete. On April 1, 1843, the Madariaga brothers and some more officials crossed the Uruguay River near Uruguaiana, on what would later be known as the 'Paso de los Libres'. With the support of some leaders like Nicanor Cáceres and Benjamín Virasoro, within thirteen days they occupied the entire province, forcing Governor Pedro Cabral to flee toward the Entre Ríos. The last federal resistance was defeated at the beginning of May in the battle of Laguna Brava. Campaigns against Rosas The Madariaga brothers convened a supportive legislature that named Joaquín Madariaga as governor. He assumed that position August 1, 1843. His first measure was to annul any measures enacted by Cabral, and sanction Ferré for having abandoned the province. He formed a unitarian party distinct from that which had supported Ferré among which were Juan Pujol, Valdez and Acosta; later, this would be the base of the liberal
