El Liberal was born as a nationalist progressive newspaper with a secular orientation and strong defense and promotion of civil and political rights.

With the management of the Castiglione family, the newspaper was reoriented to an informative journalism, opens its pages to the Catholic Church, and in its editorials shows a centrist position.

The newspaper traditionally advocates for economic, cultural, social, civil and political rights and as well for freedom of expression, environmental protection, sustainable development and free education and healthcare.

At that time, El Liberal got awards from the Inter American Press Association,[4][5] Merck & Co., University of Navarra and other national and international journalism institutions.

During the decade of 1990, many journalists of the newspaper suffered aggression from several parties, according to reports of human rights organizations, such as Amnesty International.
