Mitre was also the founder of "La Nación", one of South America's leading newspapers, in 1870. His opposition to Autonomist Party nominee Adolfo Alsina, whom he viewed as a veiled Buenos Aires separatist, led Mitre to run for the presidency again, though the seasoned Alsina outmaneuvered him by fielding Nicolás Avellaneda, a moderate lawyer from remote Tucuman Province where the independence of Argentina had been declared in 1816. The electoral college met on 12 April 1874, and awarded Mitre only three provinces, including Buenos Aires.
