Founded by Jaime and Ricardo Durán, its initial installations had belonged to La Provincia, the leading daily in Salta for much of the early 20th century. Released on August 21, 1949, El Tribuno was allied to Peronism, and provided a political counterpart to the UCR-leaning El Cívico Intransigente. Following President Perón's 1955 ouster, the paper was shuttered by the new regime, and sold at auction in 1957 to a consortium led by a local lawyer, Roberto Romero. Romero modernized the newspaper, which became one of the first to incorporate offset printing, in 1967. Romero left the post as publisher following his election as governor of Salta in 1983.
